backend: Don't create a Progression objects in 'for' loops

This patch optimizes the following pattern:

for (i in first..last step st) { ... }

In this case we need to create a Progression object and then call its
iterator() method causing at least 2 allocation per loop. This change
replaces such loops with the following constuction:

var inductionVar = first
checkProgressionStep(step)  // check if step > 0
last = getProgressionLastElement(first, last, step)
if (first <= last) {
    do {
        i = inductionVar
        inductionVar += step
        ...
    } while(i != last)
}
