Got OpenGOAL building and running natively on Apple Silicon.
This is the rest of the port after the smaller arm64 emitter PRs. I was
told pushing one big PR was okay. This covers goalc, the runtime,
linker, kernel and the GOAL asm.
The new paths have native tests. I also found four more emitter bugs
while running it. They're in scalar sqrt, 128-bit stores, scalar max and
indexed stores above 4 GB.
Spent a while cleaning it up so it's easier to read. 4am gotta sleep lol
Closes#3841

- 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
Less than 100 instructions left to implement, with the vast vast
majority being load-and-stores. These will likely be knocked out quickly
but they require a more involved implementation than just simply
translating the instructions (several need multiple instructions, others
may need reserved registers (x16 or x17 are common for this purpose))
This is a good milestone to get something pushed to master.
This PR does the following:
- Designs a mechanism by which arm64 instructions can be encoded and
emitted
- Dispatch our higher-level instruction emitting calls to either x86 or
arm64 instructions depending on what the compiler is set to (defaults to
x86)
- Bare minimum scaffolding to get the arm64 instructions successfully
executing atleast on apple silicon
- Implement enough instructions to get the codetester test suite passing
on arm
