db/comparison: Use mask information to get comparisons

Say you have something like:

unsigned int frob(unsigned int val, unsigned int mask)
{
	return val & mask;
}

Then you know that the return value is going to be <= mask.  Also it's
going to be <= val but the idiomatic way is to put the mask after the
variable.
