tree-optimization/98381 - fix live bool vector extract
This fixes extraction of live bool vector results for the case of
integer mode vectors.
2021-01-05 Richard Biener <rguenther@suse.de>
PR tree-optimization/98381
* tree.c (vector_element_bits): Properly compute bool vector
element size.
* tree-vect-loop.c (vectorizable_live_operation): Properly
compute the last lane bit offset.
