Don't emit st(0)/st(1) copies as FpMOV instructions. Use FpSET_ST? instead.
Based on a patch by Rafael Espíndola.
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
INLINEASM
with and without kills on the arguments. We don't support:
FpSET_ST1
FpSET_ST0
INLINEASM
nor
FpSET_ST1
INLINEASM
Just Don't Do It!
