2021-08-14relative branches should be shown as $+offset, not just plain offsetiximeow
while x86 branches of immediates are all relative to PC, other architectures may have absolute branches to immediate addresses, leaving this syntax ambiguous and potentially confusing. yaxpeax prefers to write relative offsets `$+...` as a rule, so uphold that here.

2021-07-01reallocate OperandCode, convert disparate registers to arrayiximeow
also remove redundant assignments of operand_count and some OperandSpec, bulk-assign all registers and operands on entry to `read_instr`. this all, taken together, shaves off about 7 cycles per decode.
2021-06-28round out x86_32 support - avx2, avx, memory sizesiximeow

also some long-mode cleanup in corresponding areas

2021-01-15fix several missing or invalid decodings among 0f01 opcodesiximeow
* `mwaitx`, `monitorx`, `rdpru`, and `clzero` are now supported * swapgs is no longer decoded in protected mode * rdpkru and wrpkru are no longer decoded if mod bits != 11
2020-11-19fix decoding of rex-prefixed modrm+sib operands selecting index 0b100 and ↵0.1.4iximeow
base 0b101 for memory operands with a base, index, and displacement either the wrong base would be selected (register number ignored, so only `*ax` or `r8*` would be reported), or yaxpeax-x86 would report a base register is present when it is not (`RegIndexBaseScaleDisp` when the operand is actually `RegScaleDisp`) thank you to Evan Johnson for catching and reporting this bug! also bump crate version to 0.1.4 as this will be immediately tagged and released.
2020-10-27fix misdecode of instructions in opcode 0x800.1.3iximeow
2020-08-09adjust public interface: public items should all be stableiximeow
`OperandCode` (obviously) wildly varies depending on how i feel on a given week, so it's now hidden to avoid people depending on numerical values of its discriminants. `RegisterBank` got a similar treatment with a new `RegisterClass` struct that's suitable for public use.

also add builders to get decoders appropriate for specific microarchitectures from intel and amd * low-power architectures are not yet present
2020-05-03add width() to ask width of an x86 operandiximeow
this is largely wrong for memory operands, which require more invasive changes
