PTH: Emitted tokens now consist of 12 bytes that are loaded used 3 32-bit loads.  This reduces user time but increases system time because of the slightly larger PTH file.  Although there is no performance win on Cocoa.h and -Eonly, overall this seems like a good step.

struct/class/union/enum types when possible, either by pointing to the
forward declaration of that type or by pointing to the definition (if
we're in the process of defining that type).

reduces malloc/free traffic of parse-noop (but no other mode),
which makes sharking -parse-noop more meaningful.
