Extend the GetInvInt table to 80 elements

This is a bug fix patch from Fraunhofer, amending/replacing/extending
the previous commit which only extended the table to 55 elements.
(In my previous fix, 55 seemed to be enough for the issue at hand at
least. A few of the coefficients had slightly different rounding than
what Fraunhofer had used though).

This will show up in AOSP in the next code drop as well.
