On Darwin, ams printer should output a second label before a jump table so the linker knows it's a new atom. But this is only needed if the jump table is put in a separate section from the function body.

as signed max tests. Along with r73717, this helps CodeGen avoid
emitting code for a maximum operation for this class of loop.

comparisons were recognized for umax, but instcombine canonicalizes
unsigned comparisons with zero to this simpler form.

Insert a SmartMutex templated class into the class hierarchy, which takes a template parameter specifying whether this mutex
should become a no-op when not running in multithreaded mode.  Make sys::Mutex a typedef of SmartMutex<false>, to preserve source compatibility.

casted induction variables in cases where the cast
isn't foldable. It ended up being a pessimization in
many cases. This could be fixed, but it would require
a bunch of complicated code in IVUsers' clients. The
advantages of this approach aren't visible enough to
justify it at this time.

C is not a low-bits mask, and add a similar instcombine for
zext((trunc(t) & C) ^ C).

When retrieving the region value, if we are going to create a symbol value, use
the cast-to type if possible.

token consumed could pop the lexer, invalidating CurPPLexer.  Thanks to
Peter Thoman for pointing it out.

- Update register allocation hint after coalescing. This is done by the target since the hint is target dependent. This is important for ARM register pair hints.
- Register allocator should resolve the second part of the hint (register number) before passing it to the target since it knows virtual register to physical register mapping.
- More fixes to get ARM load / store double word working.

needing a GRStateRef of a GRStateManager handy).
