Simplify SIMD make scripts
ax_ext.m4 no longer performs any CPU checks. Instead it just checks
if the the compile supports SIMD flags.
Runtime detection will choose the right methods base on CPU
instructions available.
Intel AVX support is still done through the build since it would
require a major refactoring of the code base to support it at runtime.
For now I added a configuration flag --enable-avx that can be used
to compile with AVX support.
Also use cpu intrinsics instead of __asm__
