[PATCH v2 09/42] i386: Helper macro for 256 bit AVX helpers

[Paul Brook]

Once all the code is in place, 256 bit vector helpers will be generated by
including ops_sse.h a third time with SHIFT=2.

The first bit of support for this is to define a YMM_ONLY macro for code that
only apples to 256 bit vectors.  XXM_ONLY code will be executed for both
128 and 256 bit vectors.
