0d9745f6eb libSyntax: teach parser to parse dictionary and array literals. (#12821) 
This commit also adds ArrayExpr and DictionaryExpr to the libSyntax nodes
family. Also, it refactors the original parser code for these two
expressions to better fit to the design of SyntaxParsingContext.

This commit has also fixed two crashers.

dfa9982edd Collapse the 17 “parse_stdlib” tests into a single test. 
The sharding of this test buys us nothing, because it was only sharding
the AST verifier, which is an insignificant portion of the runtime
(and memory usage) of this test. Given that the test takes ~2m30s to run
and consumes > 2GB memory, having 17 copies of it running is a problem.

66e13bcc85 [ConstraintSolver] Avoid unnecessarily increasing score when matching function types 
Remove function-to-function type match score increase, which should only
happen contextually in presence of other restrictions, this used to fix
the case related to matching of arrays of functions with and w/e `throws`
as function parameters which used to be ambigious, and now handled by
collection-upcast conversion score.

fe54e70fce [GSB] Don't infer requirements from types in the definitions of protocols. 
Previously, we were inferring requirements from types within the definitions
of protocols, e.g., given something like:

    protocol P {
      associatedtype A: Collection
      associatedtype B where A.Element == Set<B>
    }

we would infer that B: Hashable. The code for doing this was actually
incorrect due to its mis-use of requirement sources, causing a few
crashers. Plus, it's not a good idea in general because it hides the
actual requirements on B. Stop doing this.

Also stop trying to infer requirements from conditional
requirements---those have already been canonicalized and minimized, so
there's nothing to infer from.

e07a7362cf Add a warning that ImplicitlyUnwrappedOptional is deprecated in 4+. 
Per SE-0054, implicitly unwrapped optional is not a distinct type in the
type system, but rather just the notion that certain Optionals (denoted
by the sigil "!" rather than "?") can be implicitly unwrapped.

This is a first step in the direction of implementing this notion by
emitting a warning if the type is spelled out.

b73352af7a Disable Unsafe[Raw]BufferPointer testing in optimized mode. 
The optimized-build behavior of UnsafeBufferPointer bounds/overflow
checking cannot be tested. The standard library always compiles with debug
checking enabled, so the behavior of the optimized test depends on whether
the inlining heuristics decide to inline these methods. To fix this, we need
a way to force @_inlineable UnsafeBufferPointer methods to be emitted inside
the client code, and thereby subject the stdlib implementation to the test
case's compile options.

b5ca50619f [swiftc (67 vs. 5600)] Add crasher in swift::TypeBase::getCanonicalType(...) 
Add test case for crash triggered in `swift::TypeBase::getCanonicalType(...)`.

Current number of unresolved compiler crashers: 67 (5600 resolved)

/cc @slavapestov - just wanted to let you know that this crasher caused an assertion failure for the assertion `gpDecl->getDepth() != GenericTypeParamDecl::InvalidDepth && "parameter hasn't been validated"` added on 2017-02-22 by you in commit fdb0a186 :-)

Assertion failure in [`lib/AST/Type.cpp (line 1107)`](ab72b541f9/lib/AST/Type.cpp (L1107)):

```
Assertion `gpDecl->getDepth() != GenericTypeParamDecl::InvalidDepth && "parameter hasn't been validated"' failed.
