[PATCH 3/5] C++: clean up cp_printer

[David Malcolm <dmalcolm@redhat.com>]

This makes it easier to compare cp_printer with gcc_cxxdiag_char_table
in c-format.c.

No functional change intended.

gcc/cp/ChangeLog:
	* error.c (cp_printer): In the leading comment, move "%H" and "I"
	into alphabetical order, and add missing "%G" and "K".  Within the
	switch statement, move cases 'G', 'H', 'I' and 'K" so that the
	cases are in alphabetical order.
