Display the number of components BB vectorized
This amends the optimization message printed when a basic-block
part is vectorized to mention the number of SLP graph entries.
This helps when debugging vectorization differences and we end up
merging SLP instances for costing purposes.
2021-07-07 Richard Biener <rguenther@suse.de>
* tree-vect-slp.c (vect_slp_region): Show the number of
SLP graph entries in the optimization message.
* g++.dg/vect/slp-pr87105.cc: Adjust.
* gcc.dg/vect/bb-slp-pr54400.c: Likewise.
