The code clearing BSS already use macro or use correct instruction depending if the CPU is 32 bits or 64 bits. However, a few instructions remained 32 bits only. By using the accurate MACRO, it is now possible to deal with memory address beyond 32 bits. As a side effect, when using 64bits processor, it also divides the loop number needed to clear the BSS by 2.
