last-exclusive progressions (i.e., "until" progressions and loop over array indices). This change makes it possible to correctly implement the handling of "step" progressions. Computing the last element of a stepped progression requires that the last is inclusive. Also invert the while loop (into if + do-while) that is used when lowering for-loops over progressions that cannot overflow. This keeps the performance characteristics closer to the ForLoopsLowering in kotlin-native, since the goal is to converge to this shared version. Also used IrType instead of KotlinType, where possible. https://github.com/JetBrains/kotlin/pull/2390 https://github.com/JetBrains/kotlin/pull/2305
