[Hexagon] Add post-RA live variables analysis (#179531) ...

This patch adds HexagonLiveVariables, a post-RA liveness analysis for
physical registers, to keep block live-ins/live-outs and operand
kill/dead markers consistent after late Hexagon transforms; it is run
after GenMux in the pre-emit pipeline.
