	Revert part of 2004-04-17 change that moved -frename-registers
	to -O1.  -frename-registers is buggy.
	
	* toplev.c (flag_rename_registers): Initialize to 0.
	* doc/invoke.texi (Optimize options): Move -frename-registers
	to "Not triggered by any -O level" section.  Adjust commentary
	accordingly.
