vect: Use main loop's thresholds and VF to narrow upper_bound of epilogue
This patch uses the knowledge of the conditions to enter an epilogue loop to
help come up with a potentially more restricive upper bound.
gcc/ChangeLog:
* tree-vect-loop.c (vect_transform_loop): Use main loop's various'
thresholds to narrow the upper bound on epilogue iterations.
gcc/testsuite/ChangeLog:
* gcc.target/aarch64/sve/part_vect_single_iter_epilog.c: New test.
