f0920c0ded Fix VShift terminology 
An arithmetic shift is by definition a signed shift, and a logical shift is by definition an unsigned shift.

- Rename VectorLogicalVShiftS* -> VectorArithmeticVShift*
- Rename VectorLogicalVShiftU* -> VectorLogicalVShift*

06b31448aa emit_x64_vector: Changes to VectorSignedSaturatedDoublingMultiply 
* Return both the upper and lower parts of the multiply if required
* SSE2 does not support the pmuldq instruction, do sign correction to an unsigned result instead
* Improve port utilisation where possible (punpck instructions were a bottleneck)

e739624296 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.

463b9a3d02 ir: Add opcodes for vector paired maximum and minimums 
For the time being, we can just do a naive implementation which avoids
falling back to the interpreter a bit. Horizontal operations aren't
necessarily x86 SIMD's forte anyways.
