6ba50a9252 If an xmm register is referenced explicitly in an inline asm, make sure to 
assign it to a version of the xmm register with the regclass that matches its
type.  This fixes PR2715, a bug handling some crazy xpcom case in mozilla.

ab6c3bb44d Try approach to moving call address load inside of callseq_start. Now it's done during the preprocess of x86 isel. callseq_start's chain is changed to load's chain node; while load's chain is the last of callseq_start or the loads or copytoreg nodes inserted to move arguments to the right spot.

22bb31103d Factor out the predicate check code from DAGISelEmitter.cpp 
and use it in FastISelEmitter.cpp, and make FastISel
subtarget aware. Among other things, this lets it work
properly on x86 targets that don't have SSE, where it
successfully selects x87 instructions.

1887c1c2f9 Fix a number of byval / memcpy / memset related codegen issues.

e3d920699c Re-enable elimination of unnecessary SUBREG_TO_REG instructions in 
LowerSubregs, and fix an x86-64 isel bug that this exposed.

SUBREG_TO_REG for x86-64 implicit zero extension is only safe for
isel to generate when the source is known to always have zeros in
the high 32 bits. The EXTRACT_SUBREG instruction does not clear
the high 32 bits.

11ba3b1af6 Reapply r54147 with a constraint to only use the 8-bit 
subreg form on x86-64, to avoid the problem with x86-32
having GPRs that don't have 8-bit subregs.

Also, change several 16-bit instructions to use 
equivalent 32-bit instructions. These have a smaller
encoding and avoid partial-register updates.
