Teach tblgen to build permutations of instructions, so that the target author
doesn't have to specify them manually. It currently handles associativity,
e.g. knowing that (X*Y)+Z also matches X+(Y*Z) and will be extended in
the future.
It is smart enough to not introduce duplicate patterns or patterns that can
never match.
