History
Krzysztof Parzyszek 016e021c0d [SCEV] Look through zero-extends in howFarToZero 
An expression like
  (zext i2 {(trunc i32 (1 + %B) to i2),+,1}<%while.body> to i32)
will become zero exactly when the nested value becomes zero in its type.
Strip injective operations from the input value in howFarToZero to make
the value simpler.
