C++ PATCH to debug_tree for TYPENAME_TYPE and IDENTIFIER

[Jason Merrill]

A couple of small changes.  It was inconvenient that debug_tree didn't 
print the name of a TYPENAME_TYPE, and once it did I noticed that the 
indentation on the IDENTIFIER bits was wrong.

Tested x86_64-pc-linux-gnu, applied to trunk.

        * ptree.c (cxx_print_type) [TYPENAME_TYPE]: Dump fullname.
        (cxx_print_identifier): Correct indentation.
