An assembler able to cope with AVX instructions is now required.

All modern assemblers have this capability.  Older NASM versions
that lack the capability produce code that crashes at runtime,
so it's better to error out during the build process instead.

This reduces the local difference to the x264 upstream version.

This fixes use of uninitialized values when the FLAC encoder uses the
2-level, 4-level, and 8-level search methods. Fixes failure of the
fate-flac-24-comp-8 test when run using valgrind.

Fixes Bug 385

Also move a misplaced line from the 9_beta2 section to <next>

Previously the high end byte was always set to zero. Also get
