[vect] Re-analyze all modes for epilogues

gcc/ChangeLog:

* tree-vectorizer.c (better_epilogue_loop_than_p): Round factors up for
epilogue costing.
* tree-vect-loop.c (vect_analyze_loop): Re-analyze all modes for
epilogues, unless we are guaranteed that we can't have partial vectors.
* genopinit.c: (partial_vectors_supported): Generate new function.

gcc/testsuite/ChangeLog:

* gcc.target/aarch64/masked_epilogue.c: New test.
