    This patch improves the ability to choose a better epilogue VF when the main loop is vectorised using scalable vectors, and fixes a deficiency in https://reviews.llvm.org/D118688. The patch has no effect outside of scalable vectors and we'll be doing additional release testing on scalable vectors for LLVM 14. No issues have shown up on the build-bot that tests scalable-vectorization.
