tree-optimization/95271 - fix bswap vectorization invariant SLP type
This properly updates invariant SLP nodes vector types for bswap
vectorization.
2020-05-25 Richard Biener <rguenther@suse.de>
PR tree-optimization/95271
* tree-vect-stmts.c (vectorizable_bswap): Update invariant SLP
children vector type.
(vectorizable_call): Pass down slp ops.
* gcc.dg/vect/bb-slp-pr95271.c: New testcase.
