Accumulate the constant address offset of this GEP if possible.
This routine accepts an APInt into which it will accumulate the constant offset of this GEP if the GEP is in fact constant. If the GEP is not all-constant, it returns false and the value of the offset APInt is undefined (it is not preserved!). The APInt passed into this routine must be at exactly as wide as the IntPtr type for the address space of the base GEP pointer.

Return true if all of the indices of this GEP are zeros.
