    PR c++/39751: ICE-on-invalid parsing regression.

    This is a fix for PR c++/39751 which is an ICE-on-invalid regression in
    the C++ parser after encountering the end of file.  The one line change
    is to check that the tokens cached in DECL_PENDING_INLINE_INFO haven't
    been purged before processing them in cp_parser_late_parsing_for_member.
