tree-optimization/95582 - fix vector pattern with bool conversions
The pattern recognizer fends off against recognizing conversions
from VECT_SCALAR_BOOLEAN_TYPE_P to precision one types but what
it really needs to fend off is conversions between
VECT_SCALAR_BOOLEAN_TYPE_P types - the Ada FE uses an 8 bit
boolean type that satisfies this predicate.

* tree-vect-patterns.c (vect_recog_bool_pattern): Check
for VECT_SCALAR_BOOLEAN_TYPE_P, not just precision one.
