Ryan Houdek a0cb91daa4 Core: Adds more validation around pool buffer ownership 
All buffers should be disowned leaving their respective compilation
sites, and reowning a buffer should never have the flag already be
owned.

Throw an assert in both cases because that would be a programming error
and result in some squirrely buffer handling

Simon Scherer 21b8f8e20d x87StackOptimizationPass: Generalize ST(0) tag invalidation on pop 
UpdateTopForPop_Slow() now invalidates ST(0)'s tag by default,
so every slow-path StackPop() does this consistently instead of
the previous special case only in OP_POPSTACKDESTROY.

FINCSTP is an exception as it only moves the stack pointer without
invalidating the tag.

Pierre-Loup A. Griffais 3157685f0f DiskCache: initial anon caching 
Decode a few bytes in advance to get a hashable prefix to use as key.

Generate touched pages dynamically since they can be misaligned now, as the
cached-hit guest code isn't necessarily in the same spot as the store was.

OpcodeDispatcher: Validate instruction encodings with crc

Ryan Houdek f2c8adf7a3 OpcodeDispatcher: Validate instruction encodings with crc 
PR #5902 technically introduced a bug where we would read past the end
of bounds for thunk instructions when full smc was enabled. Luckily this
never occurs in practice as the Mono hacks never are on VDSO boundaries,
and no one is expected to enable full smc detection really.

Switch this path over to using crc32 unconditionally. This raises our
minspec technically to armv8-a+crc, but nothing that matters shipped
without crc so it's fine.

This also is a minor speed and JIT size reduction due less branches
polluting the BTB. But really only for mono/unity games.
Requires revving the DiskCache version again.

Ryan Houdek d472ce190c CMake: Always enable crc32 
This effectively raises our minspec to ARMv8.0-a + crc.
