tree-optimization/114239 - rework reduction epilogue driving
The following reworks vectorizable_live_operation to pass the
live stmt to vect_create_epilog_for_reduction also for early breaks
and a peeled main exit. This is to be able to figure the scalar
definition to replace. This reverts the PR114192 fix as it is
subsumed by this cleanup.
PR tree-optimization/114239
* tree-vect-loop.cc (vect_get_vect_def): Remove.
(vect_create_epilog_for_reduction): The passed in stmt_info
should now be the live stmt that produces the scalar reduction
result. Revert PR114192 fix. Base reduction info off
info_for_reduction. Remove special handling of
early-break/peeled, restore original vector def gathering.
Make sure to pick the correct exit PHIs.
(vectorizable_live_operation): Pass in the proper stmt_info
for early break exits.
* gcc.dg/vect/vect-early-break_122-pr114239.c: New testcase.
