The code clearing BSS already use macro or use correct instruction

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.
