Remove SkOpts_sse2.cpp.
It's sort of pointless: all our clients that will have SSE2 at runtime have it
unconditionally at compile time, so the functions in namespace portable will
pick up the SSE2 code. The procs in SkOpts_sse2.o were just duplicate code.
A couple of the procs we had in _sse2.cpp can benefit slightly when compiled
with SSSE3. I've moved those to _ssse3.cpp. This should lead to small speedups
on platforms like Linux and Windows that have a baseline of SSE2.
Similarly, I've removed the call to Init_neon() when NEON is available globally... it's a no-op.
Renaming namespace portable to something clearer is TBD.
