PR tree-optimization/60023
* tree-if-conv.c (predicate_mem_writes): Pass true instead of
false to gsi_replace.
* tree-vect-stmts.c (vect_finish_stmt_generation): If stmt
has been in some EH region and vec_stmt could throw, add
vec_stmt into the same EH region.
* tree-data-ref.c (get_references_in_stmt): If IFN_MASK_LOAD
has no lhs, ignore it.
* internal-fn.c (expand_MASK_LOAD): Likewise.
* g++.dg/vect/pr60023.cc: New test.
