Proceeding.  Thanks, Tom.  

My proposed commits are:

	1.  Fix to shortwave RRTMG to allow running with TRAPS compiled in.
	    floating point exceptions reported by Dusan and Lin. 
	2.  Fix an OpenMP threading error that was introduced in r45178 in 
	    module_DYNAMICS_ROUTINES.F90 .  Fix is to revert two ending DO
         ranges back to and ite_h2 and jte_h2.

Affected files are src/atmos/phys/grrad_nmmb.F and
src/atmos/phys/radsw_main_nmmb.F and
src/atmos/nmm/module_DYNAMICS_ROUTINES.F90 .   

Full set of differences relative to top of trunk (r46236) is in the attached
.txt file.  The code is on Tide in /gpfs/tp1/ptmp/John.Michalakes/trunk .

Unfortunately there is a failure (non bit-identical answers) in the 
NMM-B's moving nest restart regression test when running with this set 
of changes.  It's probably trivial but I'm not sure how long it will 
take to find. John, please proceed with your commit then I'll get back 
in line when this moving nest restart issue is resolved.
