Some cleanups after dyngen removal

1. hostregs_helper.h: fix comment
2. translate-all.c: rename dyngen_code(_search_pc) to
   tcg_gen_code(_search_pc)
3. tcg.c:
  - rename dyngen_table_op_count to tcg_table_op_count
  - no need to generate a log of dyngen ops generated
  - rename dyngen_code(_search_pc) to tcg_gen_code(_search_pc)
4. tcg.h: rename dyngen_code(_search_pc) to
   tcg_gen_code(_search_pc)
