    tree-optimization/118817 - fix ICE with VN CTOR simplification

    The representation of CONSTRUCTOR nodes in VN NARY and gimple_match_op
    do not agree so do not attempt to marshal between them.

            PR tree-optimization/118817
            * tree-ssa-sccvn.cc (vn_nary_simplify): Do not process
            CONSTRUCTOR NARY or update from CONSTRUCTOR simplified
            gimple_match_op.

            * gcc.dg/pr118817.c: New testcase.
