Subzero: Improve debugging controls, plus minor refactoring.
1. Decorate the list of live-in and live-out variables with register assignments in the dump() output. This helps one to assess register pressure.
2. Fix a bug where the DisableInternal flag wasn't being honored for function definitions.
3. Add a -translate-only=<symbol> to limit translation to a single function or global variable. This makes it easier to focus on debugging a single function.
4. Change the -no-phi-edge-split option to -phi-edge-split and invert the meaning, to better not avoid the non double negatives.
