2020-08-09avoid a bunch of checks in the likely display pathiximeow
rep_any will get speculated `false` quite quickly, whereas checking if the opcode is a string instruction will be costly no matter what. in the rare case rep_any is true, i don't care how costly displaying the instruction is - string instructions are relatively rare, and rep movs is typically not more than one instance when it shows up.

the arms of the match in regspec_label referenced tables that were not const. consequently, they would be rebuilt when reached, every time the match is incanted. this holds through even when regspec_label is inlined. each arm could be a const array for a small and easy change, but to avoid the indirect dispatch on spec.bank i've reorganized register names into a single const array and selected values for `RegisterBank` such that indices into that array can be formed. for my next trick, i may make `REG_NAMES` a `*const u8`, with indices picking offsets into the table - 8-byte offsets might do? this should compact down size a little more by removing a pointer and size qword for each string.
2020-08-09significantly reorganize what operands are unlikelyiximeow
likely operands are now also required to have contiguous special cases 0..31. this is to avoid generating a massively sparse jump table for no reason twice - once for unlikely_operands is quite enough as-is. this will undoubtedly be a wildly annoying maintenance burden. if this pans out (initial expiriments suggest it might) then maybe a macro will do...
