672e550601 Same isPhysRegAvailable bug as local register allocator.

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.

0fe71e9bb1 Treat clobber operands like early clobbers: if we have

7cbeb2431c Fix a (harmless) but where vregs were added to the used reg lists for 
inline asms.

Fix PR2078 by marking aliases of registers used when a register is 
marked used.  This prevents EAX from being allocated when AX is listed
in the clobber set for the asm.
