c3b0b5ca1d Move the setOperationAction(ISD::DEBUG_LOC, MVT::Other, Expand) and
the check to see if the assembler supports .loc from X86TargetLowering
into the superclass TargetLowering.

0488db9b99 Added support for new condition code modeling scheme (i.e. physical register dependency). These are a bunch of instructions that are duplicated so the x86 backend can support both the old and new schemes at the same time. They will be deleted after
all the kinks are worked out.

48d1e4517e When mixing SSE and x87 codegen, it's possible to
have situations where an SSE instruction turns into
multiple blocks, with the live range of an x87
register crossing them.  To do this correctly make
sure we examine all blocks when inserting
FP_REG_KILL.  PR 1697.  (This was exposed by my
fix for PR 1681, but the same thing could happen
mixing x87 long double with SSE.)

9b4baf1692 claim that "st" is from the 80-bit register file. This causes x87-using inline
asm to die with:

ScheduleDAG.cpp:269: failed assertion `false && "Couldn't find the register class"'

instead of:
failed assertion `RegMap->getRegClass(VReg) == RC && "Register class of operand and regclass of use don't agree!"'

yay.

f1fc3a8fa6 Fix PR 1681. When X86 target uses +sse -sse2,
keep f32 in SSE registers and f64 in x87.  This

double variants to do different things.

85dbe1a1d2 Initial support for multi-result patterns:
1.
[(set GR32:$dst, (add GR32:$src1, GR32:$src2)),
 (modify EFLAGS)]
This indicates the source pattern expects the instruction would produce 2 values. The first is the result of the addition. The second is an implicit definition in register EFLAGS.
2.
def : Pat<(parallel (addc GR32:$src1, GR32:$src2), (modify EFLAGS)), ()>
Similar to #1 except this is used for def : Pat patterns.
