Automatically use VEX-encoding in AVX/AVX2/XOP/FMA3/FMA4
functions for all instructions that exists in a VEX-encoded
version.

This change makes it easier to extend existing code to use AVX2.

Also add support for AVX emulation of a few instructions that
were missing before.

Normally, all channel ids are between 0 and 10, while they in
uncommon cases can have values up to 64k.

This avoids allocating two arrays for up to 64k entries (at a total
of over 6 MB in size) each when most of them aren't used at all.

It appears this bug originates from a "work in progress" patch from
ffmpeg-devel that was heavily redesigned by and integrated in libav

And that patch even had a reply and review on the mailing list pointing
out that it had a bug.

This fixes a deadlock with ffserver

See: [FFmpeg-devel] [PATCH] Fix HTTP authentication problem for POST actions.
     [FFmpeg-devel] [PATCH 1/3] Introduce auth_phase flag, which will be true if authorization needs to be sent, but the type of authorization is not known yet Partial fix #3036
     [FFmpeg-devel] [PATCH 2/3] Only add Transfer-Encoding header when not in authorization phase, because server will wait (indefinitely) for data when receiving this header Partial fix #3036
     [FFmpeg-devel] [PATCH 3/3] Only allow posting data and/or forcing a 200 code, enabling posting isml chunks, -after- we did a possible first request to get a 403 from the server telling us which type of authentication to apply Final part fix #3036
