Some parts were an experience, and I suppose
this commit introduces minor amounts of duplicate code
(I am not exactly sure what ASMUtil's shiftDownByDesc is supposed
to do anymore - however the newly introduced moveStackHead
method is documented properly this time to avoid wasting time
writing duplicate code)
