  llvm-reduce: Add opcode reduction pass

Try some dumb strength reductions to "simpler" opcodes.
Make some opcode substitutions I typically try to get smaller
MIR out of codegen. This is a bit target specific and I have a
lot of increasingly target specific modifications I try
during manual reduction.
