reload_combine vs. exceptions

Thanks.  It occured to me that we don't need to call control_flow_insn_p twice 
on the same insn, hence the attached patch.  It also reverses the only loop 
among 5 otherwise equivalent ones that runs backward for no valid reason.

Bootstrapped/regtested on i586-suse-linux, applied on the mainline.

	* postreload.c (reload_combine): Call control_flow_insn_p only once.
	Reverse backward loop.  Fix formatting issues.
