Some neon tests, plus the fix they needed to run at all.
`ldr q` and `str q` with a register offset had a bad option field so
they don't
decode. The s8 load was ignoring addr2 and reading from the base on its
own. A
few used post indexed forms, which move the address register.
Rest of the avx list to come.
- Adds `capstone` as a disassembling library that could eventually
replace Zydis (for now left that alone)
- Replicates all of the existing x86 tests to ARM64, fixed a bunch of
underlying issues along the way
- There are a very small handful of tests remaining that need to be
enabled / fixed
All that remains (8 instructions) are division, and NEON instructions
that require me to convert the x86 control byte to NEON `TBL` values.
Those handful of instructions can be done later while doing the next
steps (finally something more interesting than just encoding
instructions).
