c++: Fix printing of decltype(nullptr) [PR97517]
The C++ printer doesn't handle NULLPTR_TYPE, so we issue the ugly
"'nullptr_type' not supported by...". Since NULLPTR_TYPE is
decltype(nullptr), it seemed reasonable to handle it where we
handle DECLTYPE_TYPE, that is, in the simple-type-specifier handler.
gcc/cp/ChangeLog:
PR c++/97517
* cxx-pretty-print.c (cxx_pretty_printer::simple_type_specifier): Handle
NULLPTR_TYPE.
(pp_cxx_type_specifier_seq): Likewise.
(cxx_pretty_printer::type_id): Likewise.
gcc/testsuite/ChangeLog:
PR c++/97517
* g++.dg/diagnostic/nullptr.C: New test.
