Removing the whole

  if (debug_info_level < DINFO_LEVEL_TERSE
      || (TYPE_CONTEXT (type)
          && TREE_CODE (TYPE_CONTEXT (type)) != FUNCTION_DECL
          && TREE_CODE (TYPE_CONTEXT (type)) != NAMESPACE_DECL))
    TYPE_CONTEXT (type) = NULL_TREE;

block causes us to ICE for gcc.c-torture/execute/20111208-1.c and
gcc.c-torture/execute/pr42833.c

Even though I think that would be the correct thing to do.

Reduced testcase for that ICE:

int main ()
{
  {
    union { } v;  
  }
}

works with

int main ()
{
  union { } v;  
}
