Improve constant folding of vector lowering with vector bools
This improves the situation somewhat when vector lowering tries
to access vector bools as seen in PR96814.
2020-09-03 Richard Biener <rguenther@suse.de>
* tree-vect-generic.c (tree_vec_extract): Remove odd
special-casing of boolean vectors.
* fold-const.c (fold_ternary_loc): Handle boolean vector
type BIT_FIELD_REFs.
