7a43b3150b Fixes bug in frontend displacement calculation 
When an instruction had a literal and also a SIB displacement then this
was causing it to be calculated incorrectly.

58e019fbf1 Disabled AVX512 reporting in CPUID 
We don't support it and it'll be something we won't want to support for
a long time.

1b751f11dc Fixes a bug in BitSet 
If the number of nodes in a bitset grew too large then it wouldn't fit
in that calculation.

6d92146578 Flesh out X86Tables some more 
Adds an EVEX table and throws some ops in to an unimplemented function.
This is necessary for multiblock in the future where it will see
unsupported instructions but not actually execute them.

d32ebc0de0 Signal our lack of support for CET shadow stacks 
Needed to support binaries linked with glibc 2.30 and later.

glibc doesn't actually check CPUID, as kernel support is needed.
Instead, it just calls ARCH_CET_STATUS and checks for an error.

c21f711417 Adds a JitSymbols interface 
This allows linux perf to see execution inside of JIT functions.
This could be extended in the future to support something like vtune or
oprofile.

1dbeff462c Fixes Redundant Context Load Elimination pass 
Allows other passes to see more things it can optimize
`ReplaceAllUsesWith` is a bit of a trap and needs to be replaced.

199cfd76d8 Refactor IR and other changes that are hard to split 
I had to change how blocks are represented to make it easier to parse
This required a fairly substantial refactor that makes it so blocks are
represented differently and we can walk them sequentially.

This will make future analysis easier to deal with.
Had to rewrite the passes and core's parsing of the IR afterwards.

Moved RA in to a optimization pass to be shared between the JIT backends
This works because x86-64 and AArch64 RA can be identical.

Still doesn't support PHI nodes or spilling correctly, this is the first
step in the process of getting there.

that were using them to a new version instead.
