Do not CopyFromReg physregs for live-in values. Instead, create a vreg for
...
each live in, and copy the regs from the vregs. As the very first thing we
do in the function, insert copies from the pregs to the vregs. This fixes
problems where the token chain of CopyFromReg was not enough to allow reordering
of the copyfromreg nodes and other unchained nodes (e.g. div, which clobbers
eax on intel).

1. Teach LegalizeDAG how to better legalize CTTZ if the target doesn't have
CTPOP, but does have CTLZ
2. Teach PPC32 how to do sub x, const -> add x, -const for valid consts

4. Teach PPC32 that ISD::CTLZ -> PPC::CNTLZW
