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.

701975ad1d Add parsing support for @unknown (SE-0192) 
This is our first statement attribute, made more complicated by the
fact that a 'case'/'default' isn't really a normal statement. I've
chosen /not/ to implement a general statement attribute logic like we
have for types and decls at this time, but I did get the compiler
parsing arbitrary attributes before 'case' and 'default'. As a bonus,
we now treat all cases within functions as being switch-like rather
than enum-like, which is better for recovery when not in a switch.

94c3f55117 libSyntax: extract meta-information of trivia kinds to syntax_gyb_support. NFC 
The existing libSyntax infrastructure uses external python
dictionaries to share logic between C++ and Swift implementations.
This patch teaches trivia kinds to adapt to this infrastructure
 as well.
