    tree-optimization/110332 - fix ICE with phiprop

    The following fixes an ICE that occurs when we visit an edge
    inserted load from the code validating correctness for inserting
    an aggregate copy there.  We can simply skip those loads here.

            PR tree-optimization/110332
            * tree-ssa-phiprop.cc (propagate_with_phi): Always
            check aliasing with edge inserted loads.

            * g++.dg/torture/pr110332.C: New testcase.
            * gcc.dg/torture/pr110332-1.c: Likewise.
            * gcc.dg/torture/pr110332-2.c: Likewise.=
