opcode data tables made consistent. apologies for the mem::transmutes,
that's to avoid an extra load and strongly guide the compiler towards
doing a u16 load.
also fix issue where byte iter was a ref to a ref, and other small
changes.

(this nets another 15% runtime improvement)

inlining is really weird here... it seems like some inlining threshold is reached and everything goes sideways - this commit causes a 33% regression from de-trait-objecting and then a 25% improvement from inline hints
overall it seems performance should be better than it is, but codegen seems subpar. see read_imm_signed and friends
