* regrename.c (find_oldest_value_reg): Ignore the value chain if
the original register was copied in a mode with a fewer number of
hard registers than the desired mode.
(copyprop_hardreg_forward_1): Likewise.
(debug_value_data): Fix loop test.
* toplev.c (parse_options_and_default_flags): Reenable
-fcprop-registers at -O1.
