9bba894596 When trying to fold X86::SETCC into a Select, make a copy if it has more than 
one use. This allows more CMOV instructions.

71fb9ad5d9 Remove the uses of STATUS flag register. Rely on node property SDNPInFlag, 
SDNPOutFlag, and SDNPOptInFlag instead.

6892f28e99 SSE does not support i64 SINT_TO_FP (FP stack doesn't either, but we custom 
expand it), so ask legalizer to expand i32 UINT_TO_FP.

362071d7d4 use proper (82-bit) spills/fills when spilling FP regs, so that 
divides don't get broken. this fixes obsequi, smg2000, and probably
a bunch of other stuff (tm)

a243db8c41 Fix calls that need to store values in stack slots, to not copy the stack 
pointer.  This allows us to emit stuff like this:

        li r10, 0
        stw r10, 56(r1)
        or r3, r10, r10
        or r4, r10, r10
        or r5, r10, r10
        or r6, r10, r10
        or r7, r10, r10
        or r8, r10, r10
        or r9, r10, r10
        bl L_bar$stub

instead of this:

        or r2, r1, r1     ;; Extraneous copy.
        li r10, 0
        stw r10, 56(r2)
        or r3, r10, r10
        or r4, r10, r10
        or r5, r10, r10
        or r6, r10, r10
        or r7, r10, r10
        or r8, r10, r10
        or r9, r10, r10
        bl L_bar$stub

wowness.

b9169ceb23 Use Evan's outflag stuff to implement V8cmpicc. This allows us to write a 
pattern for SUBCCrr, and makes it trivial to add support for SUBCCri, eliminating
an instruction in the common "setcc X, imm" case.
