; This test case tests the InstructionCombining optimization that
; reduces things like:
;   %Y = cast sbyte %X to uint
;   %C = setlt uint %Y, 1024
; to
;   %C = bool true
; It includes test cases for different constant values, signedness of the
; cast operands, and types of setCC operators. In all cases, the cast should
; be eliminated. In many cases the setCC is also eliminated based on the
; constant value and the range of the casted value.
