c++: add missing -Wc++??-extensions checks
The pedwarns for each of these features should be silenced by
the appropriate -Wno-c++??-extensions.
The handle_pragma_diagnostic_impl change is necessary so that we handle
-Wc++23-extensions early so it's available to interpret_float while lexing.
gcc/c-family/ChangeLog:
* c-pragma.cc (handle_pragma_diagnostic_impl): Also handle
-Wc++23-extensions early.
* c-lex.cc (interpret_float): Use -Wc++23-extensions for extended
floating point literal pedwarn.
gcc/cp/ChangeLog:
* parser.cc (cp_parser_simple_type_specifier): Use
-Wc++20-extensions for auto parameter pedwarn.
* pt.cc (do_decl_instantiation, do_type_instantiation): Use
-Wc++11-extensions for 'extern template'.
gcc/testsuite/ChangeLog:
* g++.dg/cpp0x/extern_template-7.C: New test.
* g++.dg/cpp23/ext-floating19.C: New test.
* g++.dg/cpp2a/abbrev-fn1.C: New test.
