Version with profiling about psycloned_nemo

[arporter]

I've altered my script so that it permits single-line IF statements inside KERNELS regions. I've also done some experimenting and identified some files that I can now process that I couldn't previously. This makes the profile more informative if nothing else:

Most of the remaining white space is due to either global sums (especially in stp_ctl in stpctl.f90) or the packed halo exchanges (lbc_lnk_ptr in lbclnk.f90).

An update: the support for the NVTX profiling API is now on master in PSyclone.

I've (manually) tweaked traldf_iso and tra_nxt_vvl to put KERNELS in more sensible/performant locations. They've now disappeared from the profile :-)

[arporter]

I've (manually) optimised the global sums in stp_ctl - the source of the white-space on the RHS of the profiles before this one. I've also introduced a heuristic that puts KERNELS inside loops over levels when they contain 2 or more loops. The latter is essential in a couple of the big kernels but the overall performance benefit is questionable. Still, it's only a small change to the script :-)

Realised I had a bug in the script that meant that KERNELS were not being put in lower branches of CASE statements. Also realised that PSyclone can now process icetab.f90, however resulting code is slower...

Have got NEMO compiling with the latest version of PSyclone and PGI 19.10. Since the profiling API has changed I've created a new branch (profiling_new_api) in this repo. You will need to build the latest version of the nvidia wrapper library distributed with PSyclone. (See description of this Issue.) Resulting code is fastest yet:
