more SCEV cache clearing
This fixes two more places, in loop interchange and in the
vectorizer where the SCEV verifier sees stale entries.
2020-07-29 Richard Biener <rguenther@suse.de>
* tree-vectorizer.c (vectorize_loops): Reset the SCEV
cache if we removed any SIMD UID SSA defs.
* gimple-loop-interchange.cc (pass_linterchange::execute):
Reset the scev cache if we interchanged a loop.
