[MITgcm-devel] linux_amd64_ifort+mpi_ice_nas update

I will also give it a try with hi-res llc config and let you know if anything pops out.

My guess is that problem is an old compiler bug that has long been fixed.
I added the exception some 3 years ago to fix an HSALT problem.
With all the code and compiler changes since, it's very unlikely that that
problem is still there.
