Modified files:
	gcc            : ChangeLog 
	gcc/config/alpha: alpha.c alpha.md 

Log message:
	* alpha.c (add_operand): Simplify the CONST_INT match.
	(sext_add_operand): Correct typo in comparison by using
	CONST_OK_FOR_LETTER_P.
	* alpha.md (s?addq): Use sext_add_operand to allow the negative
	constant alternatives to be generated.
	(mulsi3, muldi3, umuldi3_highpart): Loosen constraints to allow
	small constants, since the hw instructions do.
