Merge pull request #1450 in HDFFV/hdf5 from ~SONGYULU/hdf5_ray:TRILAB-98-dt_arith-and-cpp_testhdf5-tests to develop
* commit 'b02de315b93ac29d2483a91d526b110a25073505': NNSA Tri-LabsTRILAB-98: Another two test cases out. NNSA Tri-Labs TRILAB-98: Taking out a few more test cases. NNSA Tri-Labs TRILAB-98 dt_arith and cpp_testhdf5 tests fail on sierra.llnl.gov: According to the group decision, simply provide a macro to disable some failing test cases on sierra (IBM power9 cpu). All failing cases involve long double data type.
