36a0947820 Eliminate more uses of llvm-as and llvm-dis.

ae3a0be92e Split the Add, Sub, and Mul instruction opcodes into separate
integer and floating-point opcodes, introducing
FAdd, FSub, and FMul.

For now, the AsmParser, BitcodeReader, and IRBuilder all preserve
backwards compatability, and the Core LLVM APIs preserve backwards
compatibility for IR producers. Most front-ends won't need to change
immediately.

This implements the first step of the plan outlined here:

3fb2968f2f make the vector conversion magic handle multiple results.
We now compile test2/test3 to:

_test2:
	## InlineAsm Start
	set %xmm0, %xmm1
	## InlineAsm End
	addps	%xmm1, %xmm0
	ret
_test3:
	## InlineAsm Start
	set %xmm0, %xmm1
	## InlineAsm End
	paddd	%xmm1, %xmm0
	ret

as expected.

41f6259a4b add support for multiple return values in inline asm. This is a step
towards PR2094.  It now compiles the attached .ll file to:

_sad16_sse2:
	movslq	%ecx, %rax
	## InlineAsm Start
	%ecx %rdx %rax %rax %r8d %rdx %rsi
	## InlineAsm End
	## InlineAsm Start
	set %eax
	## InlineAsm End
	ret

which is pretty decent for a 3 output, 4 input asm.
