Implement the getRegForInlineAsmConstraint method for PPC. With recent

sdisel changes, this eliminates a ton of copies around common inline asms.
For example:
int test2(int Y, int X) {
asm("foo %0, %1" : "=r"(X): "r"(X));
return X;
}
now compiles to:
_test2:
foo r3, r4
blr
instead of:
_test2:
mr r2, r4
foo r2, r2
mr r3, r2

GCC produces:

no fixes physreg. Treat this as permission to use any register in the register
class. When this happens and it is safe, allow the llvm register allcoator to
allocate the register instead of doing it at isel time. This eliminates a ton
