edd795e991 a64_emit_x64: Fix stack misalignment on Windows for 128-bit exclusive writes 
Discovered by @Subv.
Includes a test to ensure this codepath is exercised on Windows.

04b4c8b0cf emit_x64_aes: Eliminate extraneous usage of a scratch register in EmitAESInverseMixColumns() 
We can just use the same register the data is in as the result register,
eliminating the need to use a completely separate register to store the
result.

4606a081c9 A64: The A64SetTPIDR IR instruction writes to a system register and should not be eliminated by the dead code elimination pass. 
Previously this instruction was alway eliminated, resulting in incorrect values for TPIDR_EL0.

84affdb260 safe_ops: Avoid cases where shift bases are invalid with signed values 
For example, say the converted signed type is s64, shifting left  by 63
bits would be undefined behavior.

However, given an ASL is essentially the same behavior as an LSL
we can just use an unsigned type instead of converting to a signed type.

d0274f412a safe_ops: Avoid signed overflow in Negate() 
Negation of values such as -9223372036854775808 can't be represented in
signed equivalents (such as long long), leading to signed overflow.
Therefore, we can just invert bits and add 1 to perform this behavior
with unsigned arithmetic.

0ec8dac660 emit_x64: Remove FPSCR_RoundTowardsZero() virtual function from EmitContext struct 
This code was bugged in that we were comparing if the rounding mode was
not equal to rounding towards zero. Fortunately, however, nothing uses
this function anymore, and there's already the more general
FPSCR_RMode() available, so this can be removed entirely.

f939bd0228 emit_x64_vector{_floating_point}: Add helper alias for sizing arrays relative to vector width 
Avoids needing to remember to specify the proper size of the arrays, all
that's needed is to specify the type of the array and the size will
automatically be deduced from it. This helps prevent potential oversized
or undersized arrays from being specified.

modify it to also be usable with the signed variants.

0da5e949a8 Correct typo in DataCacheOperation enum 
Fixes a typo for the InvalidateByVAToPoC enum entry. Given yuzu is the
only known user of 64-bit mode and it doesn't use this value, we can get
away with changing this.

7bce8d8757 A64: Implement URSHR (scalar) and URSRA (scalar) 
Now that the utility function is all set up from implementing SRSRA, the
unsigned variants can now be trivially implemented by modifying the
utility function to perform a logical shift right instead of an
arithmetical shift right for the unsigned case.
