After the previous changes, all traits classes provide an implementation

gcc/
        * hash-table.h (has_is_deleted, is_deleted_helper): Delete.
        (has_is_empty, is_empty_helper): Delete.
        (has_mark_deleted, mark_deleted_helper): Delete.
        (has_mark_empty, mark_empty_helper): Delete.
        (hash_table::is_deleted): Call the Descriptor unconditionally.
        (hash_table::is_empty): Likewise.
        (hash_table::mark_deleted): Likewise.
        (hash_table::mark_empty): Likewise.

OK.  Obviously dependent on prerequisites.
