[Bug libstdc++/29286] [4.0/4.1/4.2/4.3 Regression] placement new does not change the dynamic type as it should

Regarding comment #52: do you have a reasonably sized test case?  I didn't see
any problems when I ran the C++ testsuite.

I think tree-ssa-operands.c does the right thing:

    case CHANGE_DYNAMIC_TYPE_EXPR:
      get_expr_operands (stmt, &CHANGE_DYNAMIC_TYPE_LOCATION (expr), opf_use);
      return;

But there may well be something I misunderstand.
