7ef7def661 A64: Implement SQ{ADD, SUB}, and UQ{ADD, SUB}'s vector variants
Currently we implement these in terms of the scalar variants. Falling
back to the interpreter is slow enough to make it more effective than
doing that.

c41b5a3492 x64/reg_alloc: Use type alias for array returned by GetArgumentInfo()
This way if the number ever changes, we don't need to change the type in
other places.

2188765e28 ir/value: Use type alias CoprocessorInfo for std::array<u8, 8>
Provides a more descriptive label for the interface, and avoids the need
to hardcode the array size in multiple places.

54d8552177 a32_emit_x64: std::move A32::UserConfig in the constructor
This avoids a few redundant atomic increments and decrements,
considering the UserConfig instance contains a std::array of
std::shared_ptr<Coprocessor> instances.

bb93353f94 emit_x64_vector_floating_point: Correct FMA in FTZ mode
x64 rounds before flushing to zero

b393e15ab6 backend_x64: Fix bugs when FPCR.FZ=1
Bugs:
* DenormalsAreZero flushed to positive zero instead of preserving sign.
* FMAXNM/FMINNM (scalar) should perform DAZ *before* special zero handling.
* FMAX/FMIN/FMAXNM/FMINNM (vector) did not DAZ.
