small perf tweaks
clearing reg_rrr and reg_mmm more efficiently is an extremely small win, but a win read_imm_signed generally should inline well and runs afoul of some heuristic. inlining gets about 8% improved throughput on the (unrealistic) in-repo benchmark it would be great to be able to avoid bounds checks somehow; it looks like they alone are another ~10% of decode time. i'm not sure how to pull that off while retaining the generic iterator parameter. might just not be possible.
