Select i1 logical ops directly to 64-bit SALU instructions. Vector i1 values are always really in SGPRs, with each bit for each item in the wave. This saves about 4 instructions when and/or/xoring any condition, and also helps write conditions that need to be passed in vcc. This should work correctly now that the SGPR live range fixing pass works. More work is needed to eliminate the VReg_1 pseudo regclass and possibly the entire SILowerI1Copies pass. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@223206 91177308-0d34-0410-b5e6-96231b3b80d8
