Remove the files building AVX code

This feature was never completely implemented. Sure, it's nice to
build the SSE2 + SSSE3 code with the VEX prefix, which results in
better code. But the leap isn't that big anyway.

This is the first step to removing the runtime detection for the
drawhelpers. They create timebombs when we use inline functions.
