8b73de60a9 IRGen: Remove GenericTypeRequirements::ParentType 
Finally, remove the parent type metadata argument from type
constructors.

Now that type constructors don't take a parent metadata pointer,
we can hit some asserts concerning type constructors that do not
have any parameters. This happens when you define a concrete type
in a fully-constrained extension of a generic type.

A more efficient ABI would use concrete type metadata for these
cases, but that would be a bigger change that we can do later, so
for now just relax these assertions.

This resolves a runtime crasher since a circular metadata case is
no longer circular. I renamed the crasher to reference the more
specific radar since the more general issue of circular metadata
is still unresolved.

ab3f77baf2 Make SILInstruction no longer a subclass of ValueBase and 
introduce a common superclass, SILNode.

This is in preparation for allowing instructions to have multiple
results.  It is also a somewhat more elegant representation for
instructions that have zero results.  Instructions that are known
to have exactly one result inherit from a class, SingleValueInstruction,
that subclasses both ValueBase and SILInstruction.  Some care must be
taken when working with SILNode pointers and testing for equality;
please see the comment on SILNode for more information.

A number of SIL passes needed to be updated in order to handle this
new distinction between SIL values and SIL instructions.

Note that the SIL parser is now stricter about not trying to assign
a result value from an instruction (like 'return' or 'strong_retain')
that does not produce any.

80e4a2226b [ConstraintGraph] Don't try to contract edge of parameter bindings with inout attribute 
Currently edge related to the parameter bindings is contracted
without properly checking if newly created equivalence class has
the same inout & l-value requirements. This patch improves the
situation by disallowing contraction of the edges related to parameter
binding constraint where left-hand side has `inout` attribute set.

Such guarantees that parameter can get `inout` type assigned when
argument gets `l-value` type.

76a532b3af [GSB] Move a well-formed GenericSignatureBuilder to be the canonical builder. 
Once we compute a generic signature from a generic signature builder,
all queries involving that generic signature will go through a separate
(canonicalized) builder, and the original builder can no longer be used.
The canonicalization process then creates a new, effectively identical
generic signature builder. How silly.

Once we’ve computed the signature of a generic signature builder, “register”
it with the ASTContext, allowing us to move the existing generic signature
builder into place as the canonical generic signature builder. The builder
requires minimal patching but is otherwise fully usable.

Thanks to Slava Pestov for the idea!

44fb6752d2 [swiftc (57 vs. 5592)] Add crasher in swift::Parser::parseStmtForEach(...) 
Add test case for crash triggered in `swift::Parser::parseStmtForEach(...)`.

Current number of unresolved compiler crashers: 57 (5592 resolved)

/cc @rintaro - just wanted to let you know that this crasher caused an assertion failure for the assertion `StartOfControl != Tok.getLoc()` added on 2017-08-01 by you in commit 546aeb23 :-)

Assertion failure in [`lib/Parse/ParseStmt.cpp (line 1839)`](6f0c787996/lib/Parse/ParseStmt.cpp (L1839)):

```
Assertion `StartOfControl != Tok.getLoc()' failed.

When executing: ParserResult<swift::Stmt> swift::Parser::parseStmtForEach(swift::LabeledStmtInfo)
```

Assertion context:

```c++
        skipSingle();
    }
    if (Tok.is(tok::code_complete))
      return makeParserCodeCompletionStatus();

    assert(StartOfControl != Tok.getLoc());
    SourceRange ControlRange(StartOfControl, PreviousLoc);
    Container = makeParserErrorResult(new (Context) ErrorExpr(ControlRange));
    diagnose(ForLoc, diag::c_style_for_stmt_removed)
      .highlight(ControlRange);
    Status = makeParserError();
```

e7dd8c9650 [swiftc (53 vs. 5592)] Add crasher in swift::SubstitutionMap::lookupSubstitution 
Add test case for crash triggered in `swift::SubstitutionMap::lookupSubstitution`.

Current number of unresolved compiler crashers: 53 (5592 resolved)

/cc @swiftix - just wanted to let you know that this crasher caused an assertion failure for the assertion `genericSig` added on 2017-05-01 by you in commit 0aff7c0c :-)

Assertion failure in [`lib/AST/SubstitutionMap.cpp (line 120)`](5490877692/lib/AST/SubstitutionMap.cpp (L120)):

```
Assertion `genericSig' failed.

When executing: swift::Type swift::SubstitutionMap::lookupSubstitution(CanSubstitutableType) const
```

Assertion context:

```c++
  // have.
  auto genericParam = cast<GenericTypeParamType>(type);
  auto mutableThis = const_cast<SubstitutionMap *>(this);
  auto replacementTypes = mutableThis->getReplacementTypes();
  auto genericSig = getGenericSignature();
  assert(genericSig);
  auto genericParams = genericSig->getGenericParams();
  auto replacementIndex =
    GenericParamKey(genericParam).findIndexIn(genericParams);

  // If this generic parameter isn't represented, we don't have a replacement
```

ddd0666e94 IDE: Fix mismatched ErrorType check 
In one place we were calling hasError() and in another directly checking
for ErrorType; if we had a type containing an ErrorType as a structural
component, we would hit an assertion.

ab8677faab IDE: Always use the right DeclContext 
We have a hack where we use the ParsedDecl as the DeclContext,
to handle completion during function signature parsing, which
happens before the FuncDecl has been created.

While fixing this properly would require a bigger change to the
parser and AST, for now we just check if the ParsedDecl is a
child context of CurDeclContext, and only use it then.

c28ade7077 Driver: Pass the new -sil-merge-partial-modules flag 
Also pass flags to disable SIL optimization passes when merging
modules, since that's completely unnecessary.

An evolution test that used to fail with WMO disabled now passes
with this change.

7d80daf0ff [ConstraintSolver] When ranking bindings prefer type vars with literal bindings 
Change the potential binding ranking logic to prefer type variables
which don't have other type variables related to them, but have literal
bindings, over the ones that do have other type variables.

d0bc2a8611 Custom message for recursive Strideable witness 
Strideable declares a default witness for Equatable and Comparable

extension Strideable {
  @_inlineable
  public static func < (x: Self, y: Self) -> Bool {
    return x.distance(to: y) > 0
  }

  @_inlineable
  public static func == (x: Self, y: Self) -> Bool {
    return x.distance(to: y) == 0
  }
}

This witness is implemented recursively because the expectation
is that Stride != Self.  However, it is possible to implement
SignedNumeric and Strideable together and inherit this conformance
which will cause undefined behavior - usually a crash.

Provide an overload when Stride == Self and crash with custom message
that mentions that Equatable and Comparable have to be implemented
in this case.

- It's better than nothing.
