Add test case for crash triggered in `swift::ASTVisitor`.

Current number of unresolved compiler crashers: 108 (5184 resolved)

Assertion failure in [`include/swift/AST/Decl.h (line 2047)`](https://github.com/apple/swift/blob/master/include/swift/AST/Decl.h#L2047):

```
Assertion `hasAccessibility() && "accessibility not computed yet"' failed.

When executing: swift::Accessibility swift::ValueDecl::getFormalAccess(const swift::DeclContext *) const
```

Assertion context:

```
  /// consistently. If \p useDC is provided (the location where the value is
  /// being used), features that affect formal access such as \c \@testable are
  /// taken into account.

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();

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.

852cda6c75 [Conformance checking] Factor requirement environment into its own type. 
Rather than computing the requirement environment as a tuple of
(generic signature, generic environment, substitution map),
encapsulate the result in a new RequirementEnvironment
class. Moreover, create a RequirementEnvironment once and re-use it
when matching each of the witnesses, because the environment itself
doesn't change---only the substitutions do. This saves us some work
when there are multiple potential witnesses (which is common).

3e36f8f771 [swiftc (81 vs. 5179)] Add crasher in ? 
Add test case for crash triggered in `?`.

Current number of unresolved compiler crashers: 81 (5179 resolved)

Assertion failure in [`lib/Sema/ConstraintGraph.cpp (line 50)`](https://github.com/apple/swift/blob/master/lib/Sema/ConstraintGraph.cpp#L50):

```
Assertion `impl.getGraphIndex() < TypeVariables.size() && "Out-of-bounds index"' failed.

Assertion context:

```
