Prompted by your recent "-O0 patch" to »[f]ix PTX worker spill/fill«, I
used the attached patch 0001-O0-libgomp-C-C-testing.patch to run all C
and C++ libgomp testing with -O0 (for Fortran, we iterate through various
kinds of optimization levels anyway).  (There are no regressions of
OpenMP testing.)  

For OpenACC nvptx offloading, there must still be something wrong; here's
a count of the (non-deterministic!) regressions of ten runs of the
libgomp testsuite.  As private-vars-loop-worker-5.c fails most often, it
probably makes sense to look into that one first.

For avoidance of doubt, there are no such regressions if I un-apply your
patch to »[m]ove openacc vector& worker single handling to RTL«.
