[Users] CCTK_LOOP3_INT macro with Fortran and OpenMP

Yes, this certainly could very well be be untested.

I had a look at LoopControl itself
(carpet/LoopControl/src/loopcontrol_fortran.inc) where there are eg
LC_LOOP3STR_NORMAL_OMP_PRIVATE(name, i,j,k) macros.

Then looking at cctk_Loop.h there are also INTERIOR, BOUNDARY and
INTBOUNDARIES flavors eg CCTK_LOOP3_INTBND_OMP_PRIVATE(name)
which (unfortunately) has incompatible calling syntax with
LoopControl's macro (this is a bug...).

So without changing your code you would have to use (see cctk_Loop.h
lines 3223, 3468, 3445.

Thank you.

Yours,
