History
Jakob Stoklund Olesen dcd2342d32 Also pass logical ops to combineSelectAndUse. 
Add these transformations to the existing add/sub ones:

  (and (select cc, -1, c), x) -> (select cc, x, (and, x, c))
  (or  (select cc, 0, c), x)  -> (select cc, x, (or, x, c))
  (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.
