Optimize reserved register coalescing.
Reserved registers don't have proper live ranges, their LiveInterval
simply has a snippet of liveness for each def. Virtual registers with a
single value that is a copy of a reserved register (typically %esp) can
be coalesced with the reserved register if the live range doesn't
overlap any reserved register defs.
When coalescing with a reserved register, don't modify the reserved
register live range. Just leave it as a bunch of dead defs. This
eliminates quadratic coalescer behavior in i386 functions with many

Tweak to r147599 for PR10828: Move the check from the parser into sema, and use
the Semantic Powers to only warn on class types (or dependent types), where the

We finalized on the new .apple_types accelerator table format where we don't

still lookup using the basename.

Fix SpeculativelyExecuteBB to either speculate all or none of the phis
