Log:
	PR target/59644
	* config/i386/i386.h (struct machine_function): Add
	no_drap_save_restore field.
	* config/i386/i386.c (ix86_save_reg): Use
	!cfun->machine->no_drap_save_restore instead of
	crtl->stack_realign_needed.
	(ix86_finalize_stack_realign_flags): Don't clear drap_reg unless
	this function clears frame_pointer_needed.  Set
