; PR11279: Assertion !IVLimit->getType()->isPointerTy()
;
; Test LinearFunctionTestReplace of a pointer-type loop counter. Note
; that BECount may or may not be a pointer type. A pointer type
; BECount doesn't really make sense, but that's what falls out of
; SCEV. Since it's an i8*, it has unit stride so we never adjust the
; SCEV expression in a way that would convert it to an integer type.
