    c++: delayed noexcept in member function template [PR99980]

    Some time ago I noticed that we don't properly delay parsing of
    noexcept for member function templates.  This patch fixes that.

    It didn't work because even though we set CP_PARSER_FLAGS_DELAY_NOEXCEPT
    in cp_parser_member_declaration, member template declarations take
    a different path: we call cp_parser_template_declaration and return
    prior to setting the flag.

            PR c++/99980

    gcc/cp/ChangeLog:

            * parser.c (cp_parser_single_declaration): Maybe pass
            CP_PARSER_FLAGS_DELAY_NOEXCEPT down to cp_parser_init_declarator.

    gcc/testsuite/ChangeLog:

            * g++.dg/cpp0x/noexcept71.C: New test.
