more RegSpec constructor validation, fix bug in x86_64 1b reg specs
* the first four 1-byte registers, `al`, `cl`, `dl`, `bl`, can be constructed in two ways that produce "identical" `RegSpec` that are.. not. e.g. `RegSpec::al() != Regspec::rb(0)` even though `RegSpec::al().name() == RegSpec::rb(0).name()`. this corrects the `rb` constructor at least, but instructions like `4830c0` and `30c0` still produce incompatible versions of `al`. * also fix register numbering used explicit qword-sized RegSpec constructors, r12 and r13 used to produce r8 and r9
