Ryan Houdek b83cbcb33c ConstProp: Bandage fix for instcountci
Fixed offset x86 code doesn't quite solve the issue, so adjust this
heuristic just to get instcounci to stop flaking.

This code is going to heavily change soon anyway so +50 doesn't change
much.

Ryan Houdek d19b57a52e FEXCore: Get rid of DeferredSignalFaultAddress and use the InterruptFaultPage
Arm64ec introduced the InterruptFaultPage which is lower overhead since
instead of ldr+str it just turns in to a single str. We were already
allocating the space, FEXCore and the frontend signal delegator just
needed to be updated to understand the new location.

We can additionally use this in the future if we want to make deferred
async signals INSIDE the JIT only cost a single str as well.

Alyssa Rosenzweig 9d86e11a47 RegisterAllocationPass: drop AVX flag
RA should not depend on whether we support AVX, that's a huge layering
violation! and fortunately, it does not.

Alyssa Rosenzweig 7e663b91df IR: drop IRParser
Aside from its own self-test, the parser is unused and should remain that way,
since it's a maintenance burden with no real benefit. Burn it.

Alyssa Rosenzweig a2fc51fc7b IR: specify registers, not offsets for SRA
SRA is fundamentally about hardware registers, not stores into a
software-defined context. So, it should take a register instead of an offset.
This makes all the unaligned special cases unrepresentable (by design).
