re PR tree-optimization/54610 (FAIL: gcc.dg/tree-ssa/forwprop-22.c (internal compiler error) on x86 AVX targets)
PR tree-optimization/54610
* tree-ssa-forwprop.c: Include optabs.h. Don't include
tree-vectorizer.h.
(simplify_vector_constructor): Don't use vect_gen_perm_mask,
instead create the mask constant here.
* Makefile.in (tree-ssa-forwprop.o): Depend on $(OPTABS_H).
Don't depend on $(TREE_VECTORIZER_H).
* gcc.target/i386/pr54610.c: New test.
