	* sem_ch13.adb (Analyze_Record_Representation_Clause): Use "and then"
	instead of "and", because otherwise Parent_Last_Bit is read
	uninitialized in the case where it's not a tagged type, or the tagged
	parent does not have a complete rep clause.

	* stylesw.ads: Minor documentation change.

	* types.ads: Minor reformatting

	* exp_disp.ads (Apply_Access_Checks): New subprogram that takes care of
	generating the tag checks associated with dispatching calls.
	* exp_disp.adb (Apply_Access_Checks): New subprogram.
	(New_Value): This routine was previously local to expand dispatching
	calls but it is now used also by Apply_Access_Checks.
	(Expand_Dispatching_Calls): Cleanup code because the functionality of
	tag checks is now provided by Apply_Access_Checks. 
	* exp_ch6.adb (Expand_Call): Incorporate generation of tag checks in
	case of dispatching calls.
