2da84a83 - [VectorCombine] Fix iterator invalidation in foldSelectShuffle (#197914)

[VectorCombine] Fix iterator invalidation in foldSelectShuffle (#197914) A loop in foldSelectShuffle walked shuffles with a range-for while push_back-ing into the same SmallVector. Once the inner pushes grew the vector past its current heap capacity the buffer was reallocated, leaving the range-for iterator dangling. Iterate the original entries by index instead. Fixes #197910 Fixes #196709
