    tree-optimization/115232 - demangle failure during -Waccess

    For the following testcase we fail to demangle
    _ZZN5OuterIvE6methodIvEEvvQ3cstITL0__EEN5InnernwEm and
    _ZZN5OuterIvE6methodIvEEvvQ3cstITL0__EEN5InnerdlEPv and in turn end
    up building NULL references.  The following puts in a safeguard for
    faile demangling into -Waccess.

            PR tree-optimization/115232
            * gimple-ssa-warn-access.cc (new_delete_mismatch_p): Handle
            failure to demangle gracefully.

            * g++.dg/pr115232.C: New testcase.
