It would be nice to be rid of C_EXP_ORIGINAL_CODE.  It seems to be
used only for the "suggest parentheses ..." warnings.  The C++ front
end doesn't need it for that purpose ... oh, the C++ front end doesn't
issue those warnings.  Huh.  I thought it did.

Actually it would be nice to be rid of TREE_COMPLEXITY.  It bulks up
EXPR nodes to very little purpose.
