For mips64 switch statements in subroutines could generate

One fallout from this is to turn on rela relocations
for mips64 to match gas.

This turns common i1 patterns into predicated instructions:
(add (zext cc), x) -> (select cc (add x, 1), x)
(add (sext cc), x) -> (select cc (add x, -1), x)

unsigned f(unsigned s, int x) {
return s + (x>0);
}
We now produce:
cmp r1, #0
it gt

movs r2, #0
cmp r1, #0
it gt
movgt r2, #1

(xor (select cc, 0, c), x) -> (select cc, x, (xor, x, c))
The selects can then be transformed to a single predicated instruction
by peephole.
This transformation will make it possible to eliminate the ISD::CAND,
COR, and CXOR custom DAG nodes.
