Make sure -fexceptions is enabled when -fnon-call-exceptions is

Browse source 
This makes -fexceptions enabled by -fnon-call-exceptions, removing
the odd state of !flag_exceptions && flag_non_call_exceptions from
middle-end consideration.

	* common.opt (fexceptions): Mark
	EnabledBy(fnon-call-exceptions).
	* doc/invoke.texi (fnon-call-exceptions): Document this
	enables -fexceptions.
