llvm-6502/lib/Target/PowerPC/PPCInstrInfo.td
Nate Begeman 2d4c98d79b Finally fix one of the oldest FIXMEs in the PowerPC backend: correctly
flag rotate left word immediate then mask insert (rlwimi) as a two-address
instruction, and update the ISel usage of the instruction accordingly.

This will allow us to properly schedule rlwimi, and use it to efficiently
codegen bitfield operations.
