This patchset, after some prep work, provides an initial implementation of the TARGET_VECTORIZE_VEC_PERM_CONST hook for IBM Z. Only the vmrh, vmrl, and vpdi instruction are exploited so far. More instructions will be added with follow-on patches.
Bootstrapped and regression tested on s390x. As expected various occurrences of the vperm instruction get replaced with vmr* and vpdi. I'll commit the patches after giving it a few days for comments.
