43e2d107e1 [SE-0276] Implement multi-pattern catch clauses 
Like switch cases, a catch clause may now include a comma-
separated list of patterns. The body will be executed if any
one of those patterns is matched.

This patch replaces `CatchStmt` with `CaseStmt` as the children
of `DoCatchStmt` in the AST. This necessitates a number of changes
throughout the compiler, including:
- Parser & libsyntax support for the new syntax and AST structure
- Typechecking of multi-pattern catches, including those which
  contain bindings.
- SILGen support
- Code completion updates
- Profiler updates
- Name lookup changes

0d4cf76ed0 [SyntaxParse] Renew parseListSyntax() 
Optimize for libSyntax parsing.
The new 'parseListSyntax()' receives a vector storage, passes element
builder to the callback for populating the elements, then automatically
parses trailing commas. Also, it performs automatic recovery if the
element has an error (e.g. Skip until ',' or ')').

77924c4b84 [Parser] Decouple the parser from AST creation (part 2) 
Instead of creating the AST directly in the parser (and libSyntax or
SwiftSyntax via SyntaxParsingContext), make Parser to explicitly create
a tree of ParsedSyntaxNodes. Their OpaqueSyntaxNodes can be either
libSyntax or SwiftSyntax. If AST is needed, it can be generated from the
libSyntax tree.

bf18697b4f parsing, typechecking, and SILGen for #assert 
`#assert` is a new static assertion statement that will let us write
tests for the new constant evaluation infrastructure that we are working
on. `#assert` works by lowering to a `Builtin.poundAssert` SIL
instruction. The constant evaluation infrastructure will look for these
SIL instructions, const-evaluate their conditions, and emit errors if
the conditions are non-constant or false.

This commit implements parsing, typechecking and SILGen for `#assert`.

a1a6c19959 libSyntax: add a mechanism to synthesize syntax nodes in SyntaxParsingContext. 
To enhance the error-recovery of syntax parsing, this patch allows the
parser to synthesize missing nodes to satisfy the requirement of a
syntax node under parsing. As proof-of-concept, we synthesize r-braces
for function body to avoid regressing a function decl to an unknown
decl.
