fe2c0db53b [code-completion] Fix completion when deinit shows up inside a local context 
When braces are mismatched, we can have a deinit inside a function, so
ensure we don't crash in validateDecl.

28777a3c7e [Diagnostics] Coerce closure arguments to contextual type only if it is valid 
Modify TypeChecker::coerceParameterListToType to always validate and consider only
valid contextual types (contains: no undefined, error, or type variables etc.) for
argument type coercion, such logic prevents erasure of important explicitly specified
type information attached to parameters of the closure expressions being diagnosed.

90b4e8afa2 [swiftc (103 vs. 5181)] Add crasher in swift::constraints::ConstraintGraph::Change::addedTypeVariable(...) 
Add test case for crash triggered in `swift::constraints::ConstraintGraph::Change::addedTypeVariable(...)`.

Current number of unresolved compiler crashers: 103 (5181 resolved)

Assertion failure in [`lib/Sema/ConstraintGraph.cpp (line 52)`](https://github.com/apple/swift/blob/master/lib/Sema/ConstraintGraph.cpp#L52):

```
Assertion `TypeVariables[impl.getGraphIndex()] == typeVar && "Type variable mismatch"' failed.

When executing: std::pair<ConstraintGraphNode &, unsigned int> swift::constraints::ConstraintGraph::lookupNode(swift::TypeVariableType *)
```

Assertion context:

```
  // Check whether we've already created a node for this type variable.
  auto &impl = typeVar->getImpl();
  if (auto nodePtr = impl.getGraphNode()) {
    assert(impl.getGraphIndex() < TypeVariables.size() && "Out-of-bounds index");
    assert(TypeVariables[impl.getGraphIndex()] == typeVar &&
           "Type variable mismatch");
    return { *nodePtr, impl.getGraphIndex() };
  }

  // Allocate the new node.
  auto nodePtr = new ConstraintGraphNode(typeVar);
```

[swiftc (101 vs. 5181)] Add crasher in swift::ASTVisitor
 2016-11-06 10:58:58 +01:00

f168e7270c [Type checker] Use DependentMemberType instead of type variables for nested types. 
In the constraint solver, we've traditionally modeled nested type via
a "type member" constraint of the form

  $T1 = $T0.NameOfTypeMember

and treated $T1 as a type variable. While the solver did generally try
to avoid attempting bindings for $T1 (it would wait until $T0 was
bound, which solves the constraint), on occasion we would get weird
behavior because the solver did try to bind the type
variable.

With this commit, model nested types via DependentMemberType, the same
way we handle (e.g.) the nested type of a generic type parameter. This
solution maintains more information (e.g., we know specifically which
associated type we're referring to), fits in better with the type
system (we know how to deal with dependent members throughout the type
checker, AST, and so on), and is easier to reason able.

This change is a performance optimization for the type checker for a
few reasons. First, it reduces the number of type variables we need to
deal with significantly (we create half as many type variables while
type checking the standard library), and the solver scales poorly with
the number of type variables because it visits all of the
as-yet-unbound type variables at each solving step. Second, it
eliminates a number of redundant by-name lookups in cases where we
already know which associated type we want.

Overall, this change provides a 25% speedup when type-checking the
standard library.

8b44a07f58 remove nonsensical identity tests from test suite 
The test was verifying that two independently constructed
empty cocoa sets somehow had the same identity. Not sure why this used
to hold, but it's definitely not something we guarantee.

7ec26fc976 fallout of renaming on tests which rely on internals 
Some of these are kinda dubious, but I think this would be better
addressed as part of eager bridging, which will invalidate the concept
most of these are checking for.
