As shown in D82998, the basic-aa-recphi option can cause miscompiles for gep's with negative constants. The option checks for recursive phi, that recurse through a contant gep. If it finds one, it performs aliasing calculations using the other phi operands with an unknown size, to specify that an unknown number of elements after the initial value are potentially accessed. This works fine expect where the constant is negative, as the size is still considered to be positive. So this patch expands the check to make sure that the constant is also positive.
