Stop using isTwoAddress, switching to operand constraints instead.
Tell the codegen emitter that specific operands are not to be encoded, fixing JIT regressions w.r.t. pre-inc loads and stores (e.g. lwzu, which we generate even when general preinc loads are not enabled). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@31770 91177308-0d34-0410-b5e6-96231b3b80d8
