There was a patch to change GET_CODE(..) == CONST_INT to CONST_INT_P, 
and in one instance this was done incorrectly, leaving only a plain 
GET_CODE without any comparison.  I've committed the following as 
obvious after testing on x86_64-linux.

	* simplify-rtx.c (simplify_unary_operation_1): Use CONST_INT_P in
	shift simplification where it was intended.
