Adds an inblock time sampling routine to the x86-64 JIT
...
Useful for a quick overview of the time spent in a function. It isn't
amazing for profiling since it effects the time in the function by
itself.
Only useful as a reference.

Fixes multiblock and a few bugs in RA.
...
This makes it so multiblock can now be enabled with the JITs.
Results in a decent performance increase by itself.

HLT converts to Break, which is used for leaving the VM so we need to
handle that correctly.

When an instruction had a literal and also a SIB displacement then this
was causing it to be calculated incorrectly.

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.

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.

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.
