a5a403d766 Add support on x86 for having Legalize lower ISD::LOCATION to ISD::DEBUG_LOC 
instead of ISD::LABEL with a manual .debug_line entry when the assembler
supports .file and .loc directives.

5e6e93ecdc The code that used the StartLabelId label was removed, so remove the 
code that creates the label too.

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
is effectively a new codegen mode.
Change addLegalFPImmediate to permit float and
double variants to do different things.
Adjust callers.

long double to work.)

9e3d3abd93 Remove the assumption that FP's are either float or

it appears, and do something reasonable with x86

dump ConstantSDNode's.

Expand X86 backend handling of long doubles (conversions
to/from int, mostly).

b0869ed44d It's not safe to rematerialize MOV32r0 etc. by simply cloning the original 
instruction. These are implemented with xor which will modify the conditional
code. They should be rematerialized as move instructions.

Use APFloat in UpgradeParser and AsmParser.
Change all references to ConstantFP to use the
APFloat interface rather than double.  Remove

(There are still way too many places APFloat is
just a wrapper around host float/double, but we're
getting there.)
