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.
