Work around a Sun Studio 12 code generation bug involving _mm_set_epi32().

Calling a static function wrapper around _mm_set_epi32() when not
using optimisation causes Sun Studio 12's cc to emit a spurious
floating point load which confuses the assembler.  Using a macro wrapper
rather than a function steps around the problem.
