Don't emit st(0)/st(1) copies as FpMOV instructions. Use FpSET_ST? instead.
Based on a patch by Rafael EspĂndola.
Attempt to make the FpSET_ST1 hack more robust, but we are still relying on
FpSET_ST0 preceeding it. This is only for supporting really weird x87 inline
asm.
We support:
FpSET_ST0
INLINEASM
FpSET_ST0
FpSET_ST1

An x86 function returns a floating point value in st(0), and we must make sure
it is popped, even if it is ununsed. A CopyFromReg node is too weak to represent

notes:
- The instructions are being added with dummy placeholder patterns using some 256
specifiers, this is not meant to work now, but since there are some multiclasses
generic enough to accept them, when we go for codegen, the stuff will be already
there.
- Add VEX encoding bits to support YMM
- Add MOVUPS and MOVAPS in the first round
- Use "Y" as suffix for those Instructions: MOVUPSYrr, ...

Change TII::foldMemoryOperand API to require the machine instruction to be
inserted in a MBB, and return an already inserted MI.
This target API change is necessary to allow foldMemoryOperand to call
storeToStackSlot and loadFromStackSlot when folding a COPY to a stack slot
reference in a target independent way.
The foldMemoryOperandImpl hook is going to change in the same way, but I'll wait
until COPY folding is actually implemented. Most targets only fold copies and
won't need to specialize this hook at all.
