This patch does two things regarding explicit and automatical variable
mapping to offloaded devices:
* Fixes bugs with optional arguments, which are present. They were
mapped but the mapping had issues causing run-time failures.
* It now also handles absent optional arguments.
Compared to the previous patch set,** I added several OpenMP test
cases – and fixed the fallout.
Except for trivial changes to libgomp/oacc-mem.c and omp-low.c, all
changes are in fortran/trans-openmp.c and only affect optional arguments.
The patch was bootstrapped and tested on x86_64-gnu-linux w/o
offloading-support configured and with nvptx offloading.

** Included in the attached patch are the following previously posted
patches: [1] the trivial libgomp/oacc-mem.c change, [2] only the
remaining single-line change in omp-low.c, [3] the trans-openmp.c
changes (which had to be modified+extended), and [5] the test cases.
([2] and [4] are already in GCC 10.) See:
https://gcc.gnu.org/ml/gcc-patches/2019-07/threads.html#00960 for the
original patches.
PS: For full OpenMP support, (absent) optional arguments also needed
to be handled for data-share clauses.
