The RayTracer benchmark uses wrapped SIMD types. This is the most straightforward way to adapt an existing application to use the SIMD types. However, without struct promotion these fields must always reside in memory. Furthermore, since they use the generic struct assignment and initialization code, they may use integer forms of the SSE instructions, further impacting performance.

Only look for SIMD fields if a SIMD type has been found.
Also, since more cases of local struct values are no longer marked GTF_GLOB_REF, adjust the heuristics for allocating a temporary for a struct arrRef.
