Jit64: fselx - Optimize AVX packed
For the packed variant, we can skip the final MOVAPS and write the
result directly into the destination register.
Before:
66 0F 57 C0 xorpd xmm0,xmm0
66 41 0F C2 C1 06 cmpnlepd xmm0,xmm9
C4 C3 09 4B CC 00 vblendvpd xmm1,xmm14,xmm12,xmm0
44 0F 28 F1 movaps xmm14,xmm1
After:
66 0F 57 C0 xorpd xmm0,xmm0
66 41 0F C2 C1 06 cmpnlepd xmm0,xmm9
C4 43 09 4B F4 00 vblendvpd xmm14,xmm14,xmm12,xmm0
