[TypeChecker] Fix isAnyHashableType to check type variables

c20e012b66 [28396] Remove an assert that is too strict. 
Recursive references of computed properties are allowed, but warned
about.  Closures `var`s built like the one in 28396 should crash at
runtime, not crash the compiler.

51dc142fca [28419] Extend nested init-chaining diagnostics to defer statements 
This used to cause SILGen to capture and subsequently load `self` as a
constant.  Then, when the super call was SILGen’d, it assumed that
`self` would be loaded Boxed.  Diagnose before hitting SILGen so we
don’t have to pollute Lowering with code that handles `self` in this
odd position.

e36b52c25d Resolve some compiler crashers 
Crashers fixed are minor logic errors:

Patterns: Crash occurred when requesting the range of a created
Pattern.  Validity of the range should be checked before returning it
to keep the entire range valid or invalid but never both.

ParseExpr/ParsePattern: The same fixes as the ones provided in #6319

CSDiag: The generic visitor needn’t look through TypeVarTypes either.

d37e93d3c2 [QoI] While merging equivalence classes don't forget to merge fixed types (if any) 
Otherwise merging of the representative equivalence classes leaves constraint
system and graph disconnected, which might leave to incorrect solutions.

130e5fb9df [QoI] Fix computeAssignDestType to mark lvalue enforcement type variable as materializable 
Marking such type variable as "must be materializable" is going to explicitly
enforce the notion that assignment destination type can only be materializable
and situations like source expression is InOutExpr are incorrect.

possibly optinal T1, look through optinality when setting materializability of the binding.

b236244a4b [QoI] Don't try to type-check closure return statement if it involves unresolved parameters 
If return expression uses closure parameters, which have/are
type variables, such means that we won't be be able to
type-check result correctly and, unfornutately,
we are going to leak type variables from the parent
constraint system through declaration types.

db27ccff65 [QoI] Don't walk into erroneous apply expressions while validating top level code 
In `checkTopLevelErrorHandling` if apply expression did not type-check,
don't attempt walking inside of it. This accounts for the fact that we don't
erase types without type variables to enable better code complication,
so DeclRefExpr(s) or ApplyExpr with DeclRefExpr as function contained
inside would have their types preserved, which makes classification
incorrect.

4cc33978e0 [QoI] Ignore erroneous default literal types in lookup 
There might be erroneous typealiases present which re-define literal types,
so when trying to type-check something that supposed to confirm to erroneous
redeclaration by default, ignore it.

951395c5c5 [Diagnostics] Explicitly disallow solutions with unresolved types when diagnosing single expression closure bodies 
When running diagnostics for single expression closures,
explicitly disallow to produce solutions with unresolved type variables,
because there is no auxiliary logic which would handle that and it's
better to allow failure diagnosis to run directly on the closure body.

dab14d3759 [TypeChecker] Fix isAnyHashableType to check type variables 
Currently isAnyHashableType method validates only structs but
it doesn't account for situation when type is represented via type
variable with type already fixed to AnyHashable, that results in
infinite loop in the solver because restriction [hashable-to-
anyhashable] is going to add new type variable recursively.

047f7e092f [QoI] Allow computeAssignDestType to return UnresolvedType to facilitate diagnostics 
Instead of returning empty type when RValue destination of the assignment
could not be determined, let's return it unresolved directly instead and
let it be handled by coerceToType, which is going to produce special expression
(UnresolvedTypeConversionExpression) which facilitates better diagnostics.

f42fa362d1 [Diagnostics] Type-check return of the multi-statement closure without apply solutions 
Obtain type of the result expression without applying solutions,
because otherwise this might result in leaking of type variables,
since we are not reseting result statement and if expression is
sucessfully type-checked its type cleanup is going to be disabled
(we are allowing unresolved types), and as a side-effect it might
also be transformed e.g. OverloadedDeclRefExpr -> DeclRefExpr.

0936c51a96 [swiftc (83 vs. 5325)] Add crasher in swift::TypeChecker::checkAutoClosureAttr 
Add test case for crash triggered in `swift::TypeChecker::checkAutoClosureAttr`.

Current number of unresolved compiler crashers: 83 (5325 resolved)

/cc @slavapestov - just wanted to let you know that this crasher caused an assertion failure for the assertion `!typeInContext.isNull() && "no contextual type set yet"` added on 2016-12-15 by you in commit 757f253a3 :-)

Assertion failure in [`include/swift/AST/Decl.h (line 4121)`](https://github.com/apple/swift/blob/master/include/swift/AST/Decl.h#L4121):

```
Assertion `!typeInContext.isNull() && "no contextual type set yet"' failed.

When executing: swift::Type swift::VarDecl::getType() const
```

Assertion context:

```
  }

  /// Get the type of the variable within its context. If the context is generic,
  /// this will use archetypes.
  Type getType() const {
    assert(!typeInContext.isNull() && "no contextual type set yet");
    return typeInContext;
  }

  /// Set the type of the variable within its context.
  void setType(Type t);
```

4ed17f0f63 AST: Add a new 'isBeingValidated' flag to replace a couple of other flags 
Previously, validateDecl() would check if the declaration had an
interface type and use that as an indication not to proceed.

However for functions we can only set an interface type after
checking the generic signature, so a recursive call to validateDecl()
on a function would "steal" the outer call and complete validation.

For generic types, this meant we could have a declaration with a
valid interface type but no generic signature.

Both cases were problematic, so narrow workarounds were put in
place with additional new flags. This made the code harder to
reason about.

This patch consolidates the flags and establishes new invariants:

- If validateDecl() returns and the declaration has no interface
  type and the isBeingValidated() flag is not set, it means one
  of the parent contexts is being validated by an outer recursive
  call.

- If validateDecl() returns and the declaration has the
  isBeingValidated() flag set, it may or may not have an interface
  type. In this case, the declaration itself is being validated
  by an outer recursive call.

- If validateDecl() returns and the declaration has an interface
  type and the isBeingValidated() flag is not set, it means the
  declaration and all of its parent contexts are fully validated
  and ready for use.

In general, we still want name lookup to find things that have an
interface type but are not in a valid generic context, so for this
reason nominal types and associated types get an interface type as
early as possible.

Most other code only wants to see fully formed decls, so a new
hasValidSignature() method returns true iff the interface type is
set and the isBeingValidated() flag is not set.

For example, while resolving a type, we can resolve an unqualified
reference to a nominal type without a valid signature. However, when
applying generic parameters, the hasValidSignature() flag is used
to ensure we error out instead of crashing if the generic signature
has not yet been formed.

45ef0f5dfb Sema: Generic types cannot witness associated type requirements 
Until recently we didn't allow nested generic types at all.
In Swift 3, generic typealiases were added, and we forgot to
guard against them in witness matching, leading to a crash if
a generic typealias witnesses an associated type requirement.

Now that nested generic nominals are allowed too, add a check.

The diagnostic is not very good, but I'll revisit this later.

86d3828ea0 Sema: Don't recurse into validateDecl() when adding Objective-C bridgeable conformances 
This catches another case where resolveType() could cause infinite
recursion. No test case, but this prevents crashers from regressing
with a subsequent patch.

38165e266c [QoI] Strip BindOptionalExpr from assignment that discards target 
Right before generating constraints for the new system,
check if there are any BindOptionalExpr in the tree which
wrap DiscardAssignmentExpr, such situation corresponds to syntax
like - `_? = <value>`, since it doesn't really make
sense to have optional assignment to discarded LValue which can
never be optional, we can remove BOE from the tree and avoid
generating any of the uncessary constraints.

66950c1349 [swiftc (109 vs. 5294)] Add crasher in swift::constraints::ConstraintSystem::getType(...) 
Add test case for crash triggered in `swift::constraints::ConstraintSystem::getType(...)`.

Current number of unresolved compiler crashers: 109 (5294 resolved)

/cc @rudkx - just wanted to let you know that this crasher caused an assertion failure for the assertion `ExprTypes[E]->isEqual(E->getType()) && "Expected type in map to be the same type in expression!"` added on 2016-12-11 by you in commit 1139f872 :-)

Assertion failure in [`lib/Sema/ConstraintSystem.h (line 1397)`](https://github.com/apple/swift/blob/master/lib/Sema/ConstraintSystem.h#L1397):

```
Assertion `ExprTypes[E]->isEqual(E->getType()) && "Expected type in map to be the same type in expression!"' failed.

When executing: swift::Type swift::constraints::ConstraintSystem::getType(swift::Expr *)
```

Assertion context:

```

  /// Get the type for an expression.
  Type getType(Expr *E) {
    assert(hasType(E) && "Expected type to have been set!");
    assert(ExprTypes[E]->isEqual(E->getType()) &&
           "Expected type in map to be the same type in expression!");
    return ExprTypes[E];
  }

  /// Cache the type of the expression argument and return that same
  /// argument.
```

88b54dcf51 AST: More consistent behavior of Type::subst() with missing substitutions 
When SubstFlags::UseErrorTypes was on, we would return error types
if we couldn't resolve a nested type, but a missing primary parameter
would always remain unsubstituted in the result.

Now, replace primary parameters with error types also if they're
missing.
