InstCombine: form shuffles from wider range of insert/extractelements
Sequences of insertelement/extractelements are sometimes used to build vectorsr; this code tries to put them back together into shuffles, but could only produce a completely uniform shuffle types (<N x T> from two <N x T> sources). This should allow shuffles with different numbers of elements on the input and output sides as well. llvm-svn: 203229
