Avoid inserting extra nop bundles if there are enough bundles between ZOLSetup instructions and LoopEnd to create 112-bytes padding. It takes into account the bundles in the loop body.
In progress: More heuristics to be added 1) Avoid elongating if there are 112-bytes available between writing of (ls, le, and lc) and loop end. 2) Elongate the bundles after deducting the available size.
