[multiple changes]

2010-06-17  Robert Dewar  <dewar@adacore.com>

	* switch-c.ads, switch-c.adb, sem_ch13.adb: Minor reformatting.
	* sem_ch12.adb: Add pragmas Assert and Check to previous change.

2010-06-17  Gary Dismukes  <dismukes@adacore.com>

	* layout.adb (Layout_Type): Broaden test for setting an array type's
	Component_Size to include all scalar types, not just discrete types
	(components of real types were missed).
	* sem_ch3.adb (Constrain_Index): Add missing setting of First_Literal
	on the itype created for an index (consistent with Make_Index and
	avoids possible Assert_Failures).

2010-06-17  Robert Dewar  <dewar@adacore.com>

	* atree.ads, atree.adb: Add 6-parameter version of Ekind_In
	* einfo.adb: Minor code reformatting (use Ekind_In)
