2021-08-21	clarify inaccurate 32/16-bit `call/jmp [mem]` mem_size	iximeow

2021-08-21	report memory sizes for push, pop, call, ret	iximeow
	these instructions had memory sizes reported for the operand, if it was a memory operand, but for versions with non-memory operands the decoded `Instruction` would imply that non memory access would happen at all. now, decoded instructions in these cases will report a more useful memory size.
2021-07-03	factor out MemoryAccessSize	iximeow

2021-07-03	add tests for MemoryAccessSize, consistentify style on docs	iximeow

2021-07-01	reallocate OperandCode, convert disparate registers to array	iximeow
	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.
2020-05-23	add SHA, BMI1, and BMI2, complete XSAVE extension support	iximeow
	additionally: cmpcxchg{8,16}b, rdrand, rdseed, rdpid, {rd,wr}{fs,gs}base
2020-05-21	add sha, lzcnt, tsx, f16c, svm, movbe, adx, and prefetchw extensions	iximeow
	also add builders to get decoders appropriate for specific microarchitectures from intel and amd * low-power architectures are not yet present
2020-05-03	add width() to ask width of an x86 operand	iximeow
	this is largely wrong for memory operands, which require more invasive changes
