9973b31d5b Skip invalid declarations in SourceLookupCache 
Crashers 28598 and 28778 are creating invalid validation requests for the ITC
by using unqualified lookup to get the validator to jump inside of a
transitively invalid DeclContext.

Just don't load these members.

3ba6ad654b [TypeChecker] Fix lookup of the dependent type through typealias 
While trying to resolve nested type component with type parameter
as a parent, try to resolve it as dependent member directly but
if that fails go through longer resolution path which is required
in case member type is accessed using `typealias`.

67710606e6 [Parse] Move tok::amp_prefix closer to parameter list logic 
The amp_prefix token is currently tolerated in any unary expression
context and then diagnosed later by Sema. This patch changes parsing to
only accept tok::amp_prefix in its allowed position: parameter lists.

This also fixes two "compiler crasher" tests.

784df65753 Disable a test that seems to infinitely recurse on a diagnostic sometimes. 
Once the associated bug is fixed we can re-enable.

325fdd2f12 [AST] Don’t propagate all recursive properties to BoundNameAliasType. 
With the exception of “has type variable”, which affects the arena used
for storage of a BoundNameAliasType, only propagate recursive properties
from the underlying type to a BoundNameAliasType, because the other
properties (e.g., “has archetype” or “has type parameter”) pulled from
syntactic sugar don’t apply.

e6c91b3985 Start using BoundNameAliasType for non-generic typealiases in generic contexts 
Currently, when we reference a (non-generic) typealias within a
generic context, we would completely lose type sugar for the
typealias, replacing it with the underlying type. Instead, use
BoundNameAliasType for this purpose, which allows us to maintain all
of the type sugar as well as storing complete substitutions for later
use.

f9f5ebbba9 Sema: Remove DeclChecker::IsSecondPass 
The DeclChecker had three possible states:

- IsFirstPass true, IsSecondPass false. This is the 'first pass' for
  declarations that appear at the top-level, or are nested inside
  top-level types.

- IsFirstPass false, IsSecondPass true. This is the 'second pass' for
  declarations that appear at the top-level, or are nested inside
  top-level types.

- IsFirstPass false, IsSecondPass false. This was used for (some)
  local declarations.

This is unnecessarily confusing. We can eliminate the third state
by calling typeCheckDecl() twice in a few places. This allows
IsSecondPass to be removed entirely since it's now always equal to
!IsFirstPass.

8c17b925e6 [ConstraintSystem] Add TypeLoc caching to constraint system 
This is useful for explicit casts and type expressions, where
type loc and expression types might be different, and allows
constraint solver to avoid setting opened types to expressions
which resolves multiple crashes.

c6ff7b40cc [CSBindings] Look through optional types when trying to validate l-valueness of the new bindings 
When bindings are picked for particular type variable, right-hand
side of the binding might be another type variable wrapped into optional
type, when trying to determine if both sides of the binding have the
same l-valueness it's imperative to look throught optional type of the
right-hand side. Otherwise new binding might be effectively unsolvable.

9aed3e83a8 [GSB] Infer requirements from parents of types. 
A type Foo<...>.Bar may only exist conditionally (i.e. constraints on the
generic parameters of Foo), in which case those conditional requirements
should be implied when Foo<...>.Bar is mentioned.

Fixes SR-6850.

24aa030f0c [Associated type inference] Break recursive inference and fail predictably. 
There was a path through associated type inference where we would end
up recording a type witness that contained an error, but for which we
had not reported that error, which would lead to downstream
crashes. Make sure that we reject such inferences.

And because it triggers once we fix this issue... make sure break
recursion when trying to resolve type witnesses lazily.

Fixes the crash in SR-6609 / rdar://problem/36038033, but we're still
failing to infer in those cases.

8b58b0dbb4 [Type checker] Make redeclaration checking validate fewer declarations. 
Redeclaration checking was validating all declarations with the same
base name as the given declaration (and in the same general nominal
type), even when it was trivial to determine that the declarations
could not be conflicting. Separate out the easy structural checks
(based on kind, full name, instance vs. non-instance member, etc.) and
perform those first, before validation.

Fixes SR-6558, a case where redeclaration checking caused some
unnecessary recursion in the type checker.

bd56d0c83f [swiftc (58 vs. 5619)] Add crasher in swift::ArchetypeType::resolveNestedType 
Add test case for crash triggered in `swift::ArchetypeType::resolveNestedType`.

Current number of unresolved compiler crashers: 58 (5619 resolved)

/cc @DougGregor - just wanted to let you know that this crasher caused an assertion failure for the assertion `!nested.second || nested.second->isEqual(result) || (nested.second->hasError() && result->hasError())` added on 2016-11-29 by you in commit 95f1aaf4 :-)

Assertion failure in [`lib/AST/GenericSignatureBuilder.cpp (line 2748)`](066762a77f/lib/AST/GenericSignatureBuilder.cpp (L2748)):

```
Assertion `!nested.second || nested.second->isEqual(result) || (nested.second->hasError() && result->hasError())' failed.

When executing: void swift::ArchetypeType::resolveNestedType(std::pair<Identifier, Type> &) const

fe1b153cba [swiftc (55 vs. 5619)] Add crasher in swift::Type 
Add test case for crash triggered in `swift::Type`.

Current number of unresolved compiler crashers: 55 (5619 resolved)

/cc @slavapestov - just wanted to let you know that this crasher caused an assertion failure for the assertion `known != typeBindings.end()` added on 2017-01-19 by you in commit 8de0ca54 :-)

Assertion failure in [`lib/Sema/ConstraintSystem.cpp (line 1807)`](08c4f5106b/lib/Sema/ConstraintSystem.cpp (L1807)):

```
Assertion `known != typeBindings.end()' failed.

When executing: auto swift::constraints::Solution::simplifyType(swift::Type)::(anonymous class)::operator()(swift::TypeVariableType *) const
```

Assertion context:

```c++
  // Map type variables to fixed types from bindings.
  return simplifyTypeImpl(
      getConstraintSystem(), type,
      [&](TypeVariableType *tvt) -> Type {
        auto known = typeBindings.find(tvt);
        assert(known != typeBindings.end());
        return known->second;
      });
}

04a9714d9b [Type checker] Short-circuit uses of concrete typealiases in protocols. 
Hack to allow IndexDistance to become a deprecated typealias. The actual
fix here involves deeper surgery into the substitution machinery.

b6200728a6 Sema: Fix crash on invalid openUnboundGenericType() 
We can't construct a nominal type with an ErrorType as a
parent, so in the bad circular case, return a Type() instead
to bail out of transform() altogether.

0d9745f6eb libSyntax: teach parser to parse dictionary and array literals. (#12821) 
This commit also adds ArrayExpr and DictionaryExpr to the libSyntax nodes
family. Also, it refactors the original parser code for these two
expressions to better fit to the design of SyntaxParsingContext.

This commit has also fixed two crashers.

fe54e70fce [GSB] Don't infer requirements from types in the definitions of protocols. 
Previously, we were inferring requirements from types within the definitions
of protocols, e.g., given something like:

    protocol P {
      associatedtype A: Collection
      associatedtype B where A.Element == Set<B>
    }

we would infer that B: Hashable. The code for doing this was actually
incorrect due to its mis-use of requirement sources, causing a few
crashers. Plus, it's not a good idea in general because it hides the
actual requirements on B. Stop doing this.

Also stop trying to infer requirements from conditional
requirements---those have already been canonicalized and minimized, so
there's nothing to infer from.

b5ca50619f [swiftc (67 vs. 5600)] Add crasher in swift::TypeBase::getCanonicalType(...) 
Add test case for crash triggered in `swift::TypeBase::getCanonicalType(...)`.

Current number of unresolved compiler crashers: 67 (5600 resolved)

/cc @slavapestov - just wanted to let you know that this crasher caused an assertion failure for the assertion `gpDecl->getDepth() != GenericTypeParamDecl::InvalidDepth && "parameter hasn't been validated"` added on 2017-02-22 by you in commit fdb0a186 :-)

Assertion failure in [`lib/AST/Type.cpp (line 1107)`](ab72b541f9/lib/AST/Type.cpp (L1107)):

```
Assertion `gpDecl->getDepth() != GenericTypeParamDecl::InvalidDepth && "parameter hasn't been validated"' failed.

When executing: swift::CanType swift::TypeBase::getCanonicalType()
```

Assertion context:

```c++

  case TypeKind::GenericTypeParam: {
    GenericTypeParamType *gp = cast<GenericTypeParamType>(this);
    auto gpDecl = gp->getDecl();
    assert(gpDecl->getDepth() != GenericTypeParamDecl::InvalidDepth &&
           "parameter hasn't been validated");
    Result = GenericTypeParamType::get(gpDecl->getDepth(), gpDecl->getIndex(),
                                       gpDecl->getASTContext());
    break;
  }

```

4f27b78562 [swiftc (66 vs. 5600)] Add crasher in swift::TypeChecker::resolveTypeWitness 
Add test case for crash triggered in `swift::TypeChecker::resolveTypeWitness`.

Current number of unresolved compiler crashers: 66 (5600 resolved)

/cc @jtbandes - just wanted to let you know that this crasher caused an assertion failure for the assertion `(!isComplete() || isInvalid()) && "Conformance already complete?"` added on 2016-01-07 by you in commit 8cc8c5cc :-)

Assertion failure in [`lib/AST/ProtocolConformance.cpp (line 542)`](9ec6587ec3/lib/AST/ProtocolConformance.cpp (L542)):

```
Assertion `(!isComplete() || isInvalid()) && "Conformance already complete?"' failed.

When executing: void swift::NormalProtocolConformance::setTypeWitness(swift::AssociatedTypeDecl *, swift::Type, swift::TypeDecl *) const
```

Assertion context:

Add test case for crash triggered in `swift::ProtocolConformance::getTypeWitnessAndDecl`.

Current number of unresolved compiler crashers: 60 (5600 resolved)

/cc @DougGregor - just wanted to let you know that this crasher caused an assertion failure for the assertion `known != TypeWitnesses.end() && "Didn't resolve witness?"` added on 2017-05-03 by you in commit dbb973aa :-)

Assertion failure in [`lib/AST/ProtocolConformance.cpp (line 474)`](488aa70600/lib/AST/ProtocolConformance.cpp (L474)):

ea1396c364 [GSB] Only build potential archetypes for associated type "anchors". 
Use the "override" information in associated type declarations to provide
AST-level access to the associated type "anchor", i.e., the canonical
associated type that will be used in generic signatures, mangling,
etc.

In the Generic Signature Builder, only build potential archetypes for
associated types that are anchors, which reduces the number of
potential archetypes we build when type-checking the standard library
by 14% and type-checking time for the standard library by 16%.

There's a minor regression here in some generic signatures that were
accidentally getting (correct) same-type constraints. There were
existing bugs in this area already (Huon found some of them), while
will be addressed as a follow-up.

Fies SR-5726, where we were failing to type-check due to missed
associated type constraints.
