In other words, once 14841 is taken care of, the following patch should be enough.

Note the definifition for static_tree_code_type and TREE_CODE_CLASS is wrong for C++, Java,
Objective-C and some all other languages besides C.
It should be more like which is right for every language but only folds to the constant for the language
independent trees:
#define DEFTREECODE(SYM, NAME, TYPE, LENGTH) TYPE,
static const char static_tree_code_type[] = {
#include "tree.def"
'x'
};
#undef DEFTREECODE
#define TREE_CODE_CLASS(CODE) \
(__builtin_constant_p (CODE) \
&& (CODE) <= LAST_AND_UNUSED_TREE_CODE \
? static_tree_code_type[(int) (CODE)] \
: tree_code_type[(int) (CODE)])

In *.final_cleanup of cc1-i files with --enable-checking, I see
1308 occurrences of tree_code_type[CST]
979 occurrences of tree_code_length[CST]

On PPC-darwin I get about 1251.
Next up the patch for tree_code_length.
