(symbol_find_exact_noref): ... new function.
(symbol_find): Likewise...
(symbol_find_noref): ... ditto.
(resolve_symbol_value): Resolve weakrefr without setting their
values.
(S_SET_WEAK): Call hook.
(S_GET_VALUE): Follow weakref link.
(S_SET_VALUE): Clear weakrefr.
(S_IS_WEAK): Follow weakref link.
(S_IS_WEAKREFR, S_SET_WEAKREFR, S_CLEAR_WEAKREFR): New.
(S_IS_WEAKREFD, S_SET_WEAKREFD, S_CLEAR_WEAKREFD): New.
(symbol_set_value_expression, symbol_set_frag): Clear weakrefr.
