1. it wasn't applying to definitions, only declarations, e.g. int x __asm("foo")
2. multiple definitions were conflicting, they weren't getting merged.
3. the code was duplicated in several places.

unneeded bitcast is requested.  This is common for frontends who just unconditionally
cast even if the target is often the right type already.  THis prevents going into
getFoldedCast which switches on the opcode and does a bunch of other stuff before
doing the same opzn.

This speeds up getAsIdentifierInfo from being a call to a function
with a big switch to a single testl instruction.  This speeds up
the example in PR3810 by 6.2%

Handle odd registers allocation in FGR32.

its vectors based on the subobject type we're initializing and the
(unstructured) initializer list. This eliminates some malloc thrashing
when parsing initializers (from 117 vector reallocations down to 0
when parsing Cocoa.h). We can't always pre-allocate the right amount
of storage, since designated initializers can cause us to initialize
in non-predictable patterns.

different at link time.  (Frontends that want to

give their constants weak_odr linkage).
