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)

bb93353f94 emit_x64_vector_floating_point: Correct FMA in FTZ mode
x64 rounds before flushing to zero
AArch64 rounds after flushing to zero

This difference of behaviour is noticable if something would round to a smallest normalized number

76b07d6646 u128: StickyLogicalShiftRight requires special-casing for amount == 64
In this case (128 - amount) == 64, and this invokes undefined behaviour

55eaa16615 a64_emit_x64: Ensure host has updated ticks in EmitA64GetCNTPCT
Discovered by @Subv.
Fixes incomplete fix begun in 5a91c94dca47c9702dee20fbd5ae1f4c07eef9df.
That fix fails to take into account that LinkBlock doesn't update ticks until there
are no remaining ticks to be executed.

Test added to confirm fix.
