4a9a0d07f7 backend/{a32,a64}_emit_x64: Add config entry to mask page table pointers 
Add config entry to mask out the lower bits in page table pointers.
This is intended to allow users of Dynarmic to pack small integers
inside pointers and update the pair atomically without locks.
These lower bits can be masked out due to the expected alignment in
pointers inside the page table.

For the given usage, using AND on the pointer acts the same way as a
TEST instruction. That said when the mask value is zero, TEST is still
emitted to keep the same behavior.

490160ef43 emit_x64_vector: GNFI implementation of ArithmeticShiftRightByte 
The bit-matrix is generated up-front and added to the constant-pool.
I'm using an embedded 64-bit broadcast here(m64bcst) which is the particular
EVEX encoded version of the instruction with AVX512VL+GNFI.

If it ever really matters, then we would ideally detect specific host
features like bare-GFNI and specific subsets of AVX512 and emit
the assembly based on that rather than by the entire Icelake uarch.

7df235aefb emit_x64_vector: GNFI implementation of EmitVectorLogicalShiftLeft8 
Same principle as EmitVectorLogicalShiftRight8. An 8x8 galois identity
matrix is bit-shfited to allow for arbitrary 8-bit-lane shifts.

5cc646ffed emit_x64_vector: GNFI implementation of EmitVectorLogicalShiftRight8

single-instruction implementation of a byte-lane bitshift.

multiplication(vgf2p8affineqb, Icelake), and then by reversing the bytes
themselves(pshufb, ssse3).

eb00bea1ff backend/x64/exception_handler_posix: Fix signal stack memory leak in SigHandler 
std::malloc was being called inside SigHandler's constructor without a
std::free. This doesn't really matter as SigHandler is used as a
singleton and the OS will reclaim that memory. That said, properly
freeing memory keeps -fsanitize=address quiet.
