Fix OpenACC gang-redundant execution in 'libgomp.oacc-fortran/privatized-ref-2.f90'
This was a latent problem, and this commit here now resolves a regression that
after recent commit a78b1ab1df9ca44acc5638e8f9d0ae2e62bd65ed
"amdgcn: Tune default OpenMP/OpenACC GPU utilization" we had (only) seen on a
GCN offloading '-march=gfx908' system:
{+WARNING: program timed out.+}
[-PASS:-]{+FAIL:+} libgomp.oacc-fortran/privatized-ref-2.f90 -DACC_DEVICE_TYPE_radeon=1 -DACC_MEM_SHARED=0 -foffload=amdgcn-amdhsa -O0 execution test
Same for other optimization levels.
Make sure that we're not executing non-parallelized code in gang-redundant
mode, by putting these parts into their own 'parallel' constructs, which then
default to 'num_gangs(1)'.

gang-redundant execution.
