Rewrite LinearFunctionTestReplace to handle pointer-type IVs. We've been hitting asserts in this code due to the many supported combintions of modes (iv-rewrite/no-iv-rewrite) and IV types. This second rewrite of the code attempts to deal with these cases systematically. llvm-svn: 143546

; 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.
