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

ebb8d7392c SILGen: Fix for 'try?' leaking the error value
The error is passed in to the catch block as a +1 value but
we were just dropping it on the floor.
