Log:
    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.
