Description

Tear out previous patch that completely disabled SSSE3 optimizations (and some SSE2 on SSSE3 platforms), causing us to fall back to unoptimized generic routines. Caused 30% regression in Skia benchmarks, but only in a mode that is NOT tested by our perf bots; likely responsible for 20% regression in Chrome canvas2d performance tests. Accepting this patch will break Android x86 compilation for external users, but we don't normally support that configuration.
