[OpenACC] Allow gang reductions inside serial constructs
... fixing a regression introduced in the preceding
commit 2b7dac2c0dcb087da9e4018943c023c0678234a3
"Make OpenACC orphan gang reductions errors".
gcc/fortran/
* openmp.c (oacc_is_serial, oacc_is_parallel_or_serial): New.
(resolve_oacc_loop_blocks): Use oacc_is_parallel_or_serial instead of
oacc_is_parallel.
libgomp/
* testsuite/libgomp.oacc-fortran/parallel-dims.f90: Remove
temporary skip.
