	* inline.adb, types.ads, inline.ads, frontend.adb, alloc.ads: 
	Suppress unmodified in-out parameter warning in some cases
	This patch is a also fairly significant change to the way suppressible
	checks are handled.

	* checks.ads, checks.adb (Install_Null_Excluding_Check): No check
	needed for access to concurrent record types generated by the expander.
	(Generate_Range_Check): When generating a temporary to capture the
	value of a conversion that requires a range check, set the type of the
	temporary before rewriting the node, so that the type is always
	properly placed for back-end use.
	(Apply_Float_Conversion_Check): Handle case where the conversion is
	truncating.
	(Get_Discriminal): Code reformatting. Climb the scope stack looking
	for a protected type in order to examine its discriminants.
