tree-optimization/107247 - reduce SLP reduction accumulator
The following makes sure to reduce a multi-vector SLP reduction
accumulator to a single vector using vector operations if
easily possible (if the number of lanes in the vector type is
a multiple of the number of scalar accumulators).
PR tree-optimization/107247
* tree-vect-loop.cc (vect_create_epilog_for_reduction):
Reduce multi vector SLP reduction accumulators. Check
the adjusted number of accumulator vectors against
one for the re-use in the epilogue.
