249ded3fa8 Rematerialization logic was overly conservative when it comes to loads from fixed stack slots.

dd3465eed1 Recognize loads of arguments as re-materializable first. Therefore if isReallyTriviallyReMaterializable() returns true it doesn't confuse it as a "normal" re-materializable instruction.

bcfa1ca976 Really really bad local register allocator bug. On X86, it was never using ESI, EDI, and EBP because of a bug in RALocal::isPhysRegAvailable(). For example, when
it checks if ESI is available, it then looks at registers aliases to ESI. SIL is marked -2 (not allocatable) but isPhysRegAvailable() incorrectly assumes it is in use and returns false for ESI.

d2b1fb27df copy mmx values from/to memory with GPRs on x86-32
instead of with mmx registers.  This horribleness is apparently
done by gcc to avoid having to insert emms in places that really 
should have it.  This is the second half of rdar://5741668.

149a4e56fc Start using GPR's to copy around mmx value instead of mmx regs.
GCC apparently does this, and code depends on not having to do
emms when this happens.  This is x86-64 only so far, second half
should handle x86-32.
