    tree-optimization/64731 - extend store-from CTOR lowering to TARGET_MEM=
_REF

    The following also covers TARGET_MEM_REF when decomposing stores from
    CTORs to supported elementwise operations.  This avoids spilling
    and cleans up after vector lowering which doesn't touch loads or
    stores.  It also mimics what we already do for loads.

            PR tree-optimization/64731
            * tree-ssa-forwprop.cc (pass_forwprop::execute): Also
            handle TARGET_MEM_REF destinations of stores from vector
            CTORs.

            * gcc.target/i386/pr64731.c: New testcase.=
