2047683777 emit_x64_vector: Correct static asserts for < 64-bit type checks in saturated accumulate fallbacks 
I had initially meant to use BitSize() here, not sizeof()

1076651426 emit_x64_vector: Simplify fpsr_qc related code 
Move the bool conversion into A64JitState::GetFpsr so we don't have to continuously
pay the cost of conversion for every saturation instruction.

0bb908fb53 ir: Add opcodes for vector CLZ operations 
We can optimize these cases further for with the use of a fair bit of
shuffling via pshufb and the use of masks, but given the uncommon use of
this instruction, I wouldn't consider it to be beneficial in terms of
amount of code to be worth it over a simple manageable naive solution
like this.

If we ever do hit a case where vectorized CLZ happens to be a
bottleneck, then we can revisit this. At least with AVX-512CD, this can
be done with a single instruction for the 32-bit word case.

We can simply modify the general function made for SMULL{2} and
UMULL{2}'s by-element variants to also handle the other multiply-based
by-element variants.

02357939ac ir/value: Replace includes with forward declarations 
enum classes are still considered complete types when forward declared
(as the compiler knows the exact size of the type from the declaration
alone). The only difference in this case being that the members of the
enum class aren't visible. Given we don't use the members within this
header in any way, we can simply forward declare them here and remove
the inclusions.

e335050886 emit_x64_vector: Simplify "position == 0" case for EmitVectorExtractLower() 
In the event position == 0, we can just treat it as a simple movq,
clearing the upper half of the XMM register. This also makes that case
use only one register.
