Comment (by simonpj):
John Meacham says "actually, this is not true for the specific case of
testing against zero on x86 at least. there is a 'zero flag' that is set
whenever the result
of an operation is zero. whereas for compares, you actually need to load
zero into a register and cmp against it."
