s-osinte-tru64.adb: Mark Asm statements Volatile to prevent warnings (seems a reasonable change... 

2006-10-31  Robert Dewar  <dewar@adacore.com>

	* s-osinte-tru64.adb: 
	Mark Asm statements Volatile to prevent warnings (seems a
	reasonable change anyway)
	Fixes new warnings

	* s-mastop-irix.adb: Add Volatile to Asm statements
	Suppresses warning, and seems appropriate in any case

	* s-osinte-vms.adb: Add Volatile to Asm statement

	* s-vaflop-vms-alpha.adb: Add Volatile to Asm statements

	* exp_code.ads, exp_code.adb (Asm_Input_Value): Note that Error can be
	returned.
	Add call to Check_Code_Statement
