fa73e0c64e Enable re-materialization of instructions which have virtual register operands if
the definition of the operand also reaches its uses.

a64d4179d4 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.

e70bc39d74 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.

de80982418 Fix a regression in 403.gcc and 186.crafty introduced in 47383. To test
that a value is >= 32, check that all of the high bits are zero, not
just one or more.

b3c8d120dc Make the clobber analysis a bit more smart: we only are careful about
early clobbers if the clobber list contains a *register* not some thing
like {memory}, {dirflag} etc.

4f87f1c087 Treat clobber operands like early clobbers: if we have
any, we force sdisel to do all regalloc for an asm.  This
leads to gross but correct codegen.

This fixes the rest of PR2078.

99b5a37d39 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.

aaf11abe28 Remove one of the fixmes that I put in there. From Evan:
No need to go up more levels. A def of a register also sets its sub-registers
(so if PhysRegInfo[SuperReg] is NULL, it means SuperReg's super registers are
not previously defined).
