Daniel Sanders a6cfce6863 [globalisel][tablegen] Finish fixing compile-time regressions by merging the matcher and emitter state machines. ...

Summary:
Also, made a few minor tweaks to shave off a little more cumulative memory consumption:
* All rules share a single NewMIs instead of constructing their own. Only one
  will end up using it.
* Use MIs.resize(1) instead of MIs.clear();MIs.push_back(I) and prevent
  GIM_RecordInsn from changing MIs[0].
