Ganesh Ajjanagadde	92e483f8ed	all: use FFDIFFSIGN to resolve possible undefined behavior in comparators FFDIFFSIGN was created explicitly for this purpose, since the common return a - b idiom is unsafe regarding overflow on signed integers. It optimizes to branchless code on common compilers. FFDIFFSIGN also has the subjective benefit of being easier to read due to lack of ternary operators. Tested with FATE. Things not covered by this are unsigned integers, for which overflows are well defined, and also places where overflow is clearly impossible, e.g an instance where the a - b was being done on 24 bit values.
