    * tree-vect-loop-manip.c (vect_loop_versioning): Remove code
    hoisting invariant stmts.
    * tree-vect-stmts.c (vectorizable_load): Insert the splat of
    invariant loads on the preheader edge if possible.

    * gcc.dg/torture/pr58921.c: New testcase.
    * gcc.dg/torture/pr59006.c: Likewise.
    * gcc.dg/vect/pr58508.c: XFAIL no longer handled cases.
