a3254b7990 Foundation: add custom AnyHashable representations to NSNumber and NSString 
We want NSNumbers bridged from Swift types to bridge back to the same
Swift type.

0ed9ee8dee Revert "Migrate from UnsafePointer<Void> to UnsafeRawPointer. (#3724)" 
This reverts commit ece0951924.

This results in lldb failues on linux that I can't readily debug.
Backing out until they can be resolved.

ece0951924 Migrate from UnsafePointer<Void> to UnsafeRawPointer. (#3724) 
* Migrate from `UnsafePointer<Void>` to `UnsafeRawPointer`.

As proposed in SE-0107: UnsafeRawPointer.

`void*` imports as `UnsafeMutableRawPointer`.
`const void*` imports as `UnsafeRawPointer`.

Occurrences of `UnsafePointer<Void>` are replaced with UnsafeRawPointer.

* Migrate overlays from UnsafePointer<Void> to UnsafeRawPointer.

This requires explicit memory binding in several places,
particularly in NSData and CoreAudio.

* Fix a bunch of test cases for Void->Raw migration.

* qsort takes IUO values

* Bridge `Unsafe[Mutable]RawPointer as `void [const] *`.

* Parse #dsohandle as UnsafeMutableRawPointer

* Update a bunch of test cases for Void->Raw migration.

* Trivial fix for the SceneKit test case.

* Add an UnsafeRawPointer self initializer.

This is unfortunately necessary for assignment between types imported from C.

* Tiny simplification of the initializer.

7bfaeb57f1 [SE-0081] Warn on deprecated where clause inside angle brackets 
and provide a fix-it to move it to the new location as referenced
in SE-0081.

Fix up a few stray places in the standard library that is still using
the old syntax.

Update any ./test files that aren't expecting the new warning/fix-it
in -verify mode.

While investigating what I thought was a new crash due to this new
diagnostic, I discovered two sources of quite a few compiler crashers
related to unterminated generic parameter lists, where the right
angle bracket source location was getting unconditionally set to
the current token, even though it wasn't actually a '>'.

1ae8e37058 Remove -enable-protocol-typealiases staging flag 
It looks like migration fixits are done, and this doesn't
expose any new bugs that were not possible before, because
you could already define typealiases inside protocol
extensions.

To prevent some compiler_crasher regressions, add a simple
circularity-breaking hack. I'll need to do a sweep to clean
these up some day soon.

ecc6bd51ad Type system support for raw pointer conversion. (#3685) 
* [Type System] Handle raw pointer conversion.

As proposed in SE-0107: UnsafeRawPointer.
https://github.com/apple/swift-evolution/blob/master/proposals/0107-unsaferawpointer.md#implicit-argument-conversion

UnsafeMutablePointer<T> -> UnsafeMutableRawPointer
UnsafeMutablePointer<T> -> UnsafeRawPointer
UnsafePointer<T> -> UnsafeRawPointer
UnsafeMutableRawPointer -> UnsafeRawPointer

inout:
&anyVar -> UnsafeMutableRawPointer
&anyVar -> UnsafeRawPointer

array -> UnsafeRawPointer
string -> UnsafeRawPointer

varArray -> UnsafeMutableRawPointer

* Rename expectEqual(_, _, sameValue:) to expectEqualTest to workaround a type system bug.

<rdar://26058520> Generic type constraints incorrectly applied to functions with the same name

This is exposed by additions to the type system for UnsafeRawPointer.

Warning: unit tests fail very confusingly without this fix.

89c42cc7c1 [swiftc (72 vs. 5115)] Add crasher in swift::Expr::walk(...) 
Add test case for crash triggered in `swift::Expr::walk(...)`.

Current number of unresolved compiler crashers: 72 (5115 resolved)

Assertion failure in [`lib/Sema/CSApply.cpp (line 683)`](https://github.com/apple/swift/blob/master/lib/Sema/CSApply.cpp#L683):

```
Assertion `baseTy->isAnyExistentialType() && "Type must be existential"' failed.

When executing: swift::Expr *(anonymous namespace)::ExprRewriter::openExistentialReference(swift::Expr *, swift::ArchetypeType *, swift::ValueDecl *)
```

Assertion context:

```
      if (auto metaTy = baseTy->getAs<AnyMetatypeType>()) {
        isMetatype = true;
        baseTy = metaTy->getInstanceType();
      }

      assert(baseTy->isAnyExistentialType() && "Type must be existential");

      // If the base was an lvalue but it will only be treated as an
      // rvalue, turn the base into an rvalue now. This results in
      // better SILGen.

c9c865c279 [stdlib] Update partition(by:) tests 
Adds a dispatch test for partition(by:), since it's now a protocol
requirement. Also adds a new logging collection wrapper that only
logs when _withUnsafeMutableBufferPointerIfSupported is called --
any calls to this method from dispatched methods are uncounted by
the standard logging wrappers.

a3c2f8be5b [swiftc (71 vs. 5114)] Add crasher in swift::TypeChecker::lookupMemberType(...) 
Add test case for crash triggered in `swift::TypeChecker::lookupMemberType(...)`.

Current number of unresolved compiler crashers: 71 (5114 resolved)

Assertion failure in [`lib/Sema/TypeCheckNameLookup.cpp (line 328)`](https://github.com/apple/swift/blob/master/lib/Sema/TypeCheckNameLookup.cpp#L328):

```
Assertion `!type->isTypeParameter()' failed.

When executing: swift::LookupTypeResult swift::TypeChecker::lookupMemberType(swift::DeclContext *, swift::Type, swift::Identifier, NameLookupOptions)
```

Assertion context:

```
  // Look through the metatype.
  if (auto metaT = type->getAs<AnyMetatypeType>())
    type = metaT->getInstanceType();

  // Callers must cope with dependent types directly.
  assert(!type->isTypeParameter());

  // Look for members with the given name.
