[Bug tree-optimization/21047] New: ASSERT_EXPR handling in fold never triggers.

[Bug tree-optimization/21047] New: ASSERT_EXPR handling in fold never triggers.

[kazu at cs dot umass dot edu]

According to tree.def, ASSERT_EXPR belongs to tcc_expression.

When fold gets a tree node that is tcc_expressions,
we do not get to the following switch statement.

  switch (code)
    {
    case CONST_DECL:
      return fold (DECL_INITIAL (t));

    case ASSERT_EXPR:

So the ASSERT_EXPR case never triggers.
