implement stringcmp, with extensive commenting

and a lot of other stuff necessary for that, as follows

implement the "adc" and "sbb" instructions in flatassembler (there's no Forth implementation of them yet)

implement "cmps8" in flatassembler; Forth already has a much more thorough suite of string instructions

add Forth jmp_rel_imm8 and flatassembler jmp.rel.bimm unconditional jumps. they're nver used, it just seems like they should exist.

split the disp8 case from the indirect case for the flatassembler implementation of register-to-register mov, to match how the Forth implementation works

fix the name of mov.disp8.qreg.qreg, which had been incorrectly named mov.qreg.disp8.qreg. it's never called anyway.

fix a citation for the MOV instruction; Intel's section numbers are confusing.

Force-Push: yeah
