I've reached a point where *all* targets must use the translator loop.  
Do that, plus some other obvious cleanups.

Changes for v3:
  * Improve the commentary on patch 4 (pmm).
  * Inline handle_instruction.
  * Use pc_next for pc+4 (pmm).

Changes for v2:
  * Fix (drop) singlestep check for max_insns.
    We already do that generically.
