c++: Fix pretty printing of TYPENAME_TYPEs
I noticed that in some concepts diagnostic messages, we were printing typename
types incorrectly, e.g. printing remove_reference_t<T> as
typename remove_reference<T>::remove_reference_t
instead of
typename remove_reference<T>::type.
Fix this by printing the TYPENAME_TYPE_FULLNAME instead of the TYPE_NAME in
cxx_pretty_printer::simple_type_specifier, which is consistent with how
dump_typename in error.c does it.
gcc/cp/ChangeLog:
* cxx-pretty-print.c (cxx_pretty_printer::simple_type_specifier)
[TYPENAME_TYPE]: Print the TYPENAME_TYPE_FULLNAME instead of the
TYPE_NAME.
gcc/testsuite/ChangeLog:
* g++.dg/concepts/diagnostic4.C: New test.
