There is an SSE2 implementation so the SSE version is never used. The "SSE"
version also happens to contain SSE2 instructions on x86-64.

Commit 0a551cbe introduced "activation_bytes" option, and not specifying
this option (while calling ffmpeg / ffprobe) causes the program to quit
early. Before this commit, ffprobe was capable of processing metadata in
.aax files.

This commit adds a short description to the aac_coder option of the
AAC encoder in order to be consistent with the other options.
Generally, right now, the 'FAAC' method works fine with speech and
low broadband spectrum audio. 'Fast' is just as the name suggests.
'ANMR' still needs work and 'Twoloop', the default, works well with
every type of audio.
