    libpayload: head.S: Avoid clearing BSS (and heap) again
    
    3 out of 4 architectures currently zero out the payload BSS in early
    assembly code, which is pointless since the code loading the payload has
    already done that (with a more efficient memset). ARM64 has never had
    any code like this and can run just fine without it. This also defeats
    the new optimization of moving the heap out of the BSS, since all three
    implementations assume that everything between _edata and _end is BSS.
    We should just take this out.
