; This crased at some point as we place %1 and %4 in the same equivalence class
; for invariant loads and when we remap SCEVs to use %4 instead of %1 AddRec SCEVs
; for the for.body.10 loop caused a crash as their operands were not invariant
; in the loop. While we know they are, ScalarEvolution does not. However, we can simply
; rewrite the AddRecs to hoist everything from the "start" out of the AddRec.
;
; Check we do not crash.
