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.
