x64: Fill out more AVX instructions (#5849)

* x64: Fill out more AVX instructions

This commit fills out more AVX instructions for SSE counterparts
currently used. Many of these instructions do not benefit from the
3-operand form that AVX uses but instead benefit from being able to use
`XmmMem` instead of `XmmMemAligned` which may be able to avoid some
extra temporary registers in some cases.
