Subject: [PATCH] Fix compilation errors.

vec_avx.h needs x86cpu.h, and x86cpu.h needs to detect SSE2 (or
 greater) without the Opus macros.
Also, nobody was defining OPUS_CLEAR (but several things were
 including the non-existent os_support.h where it is defined in
 libopus), so replace those calls with RNN_CLEAR and remove the
 erroneous includes.
Take the opportunity to hoist OPUS_GNUC_PREREQ to common.h, too,
 since it is needed in multiple places now.
