the DeclaratorInfo, one for semantic analysis), just build a single type whose
canonical type will reflect the semantic analysis (assuming the type is
well-formed, of course).

To make that work, make a few changes to the type system:
* allow the nominal pointee type of a reference type to be a (possibly sugared)
  reference type.  Also, preserve the original spelling of the reference type.
  Both of these can be ignored on canonical reference types.
* Remove ObjCProtocolListType and preserve the associated source information on
  the various ObjC TypeLocs.  Preserve the spelling of protocol lists except in
  the canonical form.
* Preserve some level of source type structure on parameter types, but
  canonicalize on the canonical function type.  This is still a WIP.

Drops code size, makes strides towards accurate source location representation,
slight (~1.7%) progression on Cocoa.h because of complexity drop.

Always emit error diagnostics when an error occurs within clang_createTranslationUnit() and clang_createTranslationUnitFromSource().  These kind of errors are ones that shouldn't be missed.

Use 'waitpid' instead of 'wait'.  Basing Program::Wait() on 'wait()' prevents it being correct within a multithreaded context.

This address: PR 5277 (Program::Wait is unsafe to call from multiple threads).

Note: If waitpid() turns out to be non-portable, we can add more autoconf magic, or look into
another solution.

even when keys get RAUWed and deleted during its lifetime. By default the keys
act like WeakVHs, but users can pass a third template parameter to configure
how updates work and whether to do anything beyond updating the map on each
action.

It's also possible to automatically acquire a lock around ValueMap updates
triggered by RAUWs and deletes, to support the ExecutionEngine.
