John Stiles dec5ff2286 Reland "Add ES3 intrinsics isinf/isnan to public SkSL ES3."
This reverts commit 9155b338bb.

Reason for revert: disable test for GLSL + Adreno 6xx

Original change's description:
> Revert "Add ES3 intrinsics isinf/isnan to public SkSL ES3."
>
> This reverts commit e43714f490.
>
> Reason for revert: Several Pixel (Adreno) devices failing the test
>
> Original change's description:
> > Add ES3 intrinsics isinf/isnan to public SkSL ES3.
> >
> > The ES3 spec doesn't mandate that `isnan` actually has to do anything,
> > so the Isnan test is not enabled. (It doesn't work on my personal
> > machine unless I make the NaN detectable at compile-time.)
> >
> > We do not support these functions in constant-expressions, as we
> > currently avoid optimizing anything into a non-finite value; we leave
> > expressions alone if we calculate a NaN/inf result for their value.
