// For "step" progressions in JVM IR, when the step is constant and == 1, and "step" is called on a literal progression which we already
// know to have a step whose absolute value is 1, we can essentially ignore the "step" call.
//
// Expected lowered form of loop:
//
// // Standard form of loop over progression
// var inductionVar = 1
// val last = 4
// val step = 1
// if (inductionVar <= last) {
// // Loop is not empty
// do {
// val i = inductionVar
// inductionVar += step
// // Loop body
// } while (inductionVar <= last)
// }
