[FunctionAttrs] Handle zero writes in initializes inference.
ConstantRange's constructor asserts that the range not empty, except if
lower/upper are min or max values.
Check if the length is strictly positive instead of just non-negative so
std::nullopt is returned when the size is 0. If that's the case, the
access doesn't initialize anything.
This should fix a crash when building on macOS with ASan & UBsan after
