Unable to run tests

I ran pytest -rs -sv rbc/tests/heavydb/test_array.py -x --tb=short

and received:

rbc/tests/heavydb/test_array.py::test_ptr[cpu-int8_t i1]
  /Users/bfturner/dev/omni/rbc/rbc/irtools.py:130: UserWarning: JITRemoteCodegen._get_host_cpu_features: `remove_features` dictionary requires an update: detected different LLVM versions in server (9, 0, 1) and client (10, 0, 1).

    f'{type(self).__name__}._get_host_cpu_features: `remove_features` dictionary'

-- Docs: https://docs.pytest.org/en/stable/how-to/capture-warnings.html

so I added the following to remove_features dictionary

(9, 10): ['sse2', 'cx16', 'sahf', 'tbm', 'avx512ifma', 'sha', 'gfni',
                      'fma4', 'vpclmulqdq', 'prfchw', 'bmi2', 'cldemote', 'fsgsbase',
                      'ptwrite', 'xsavec', 'popcnt', 'mpx', 'aes', 'avx512bitalg',
                      'movdiri', 'xsaves', 'avx512er', 'avx512vnni', 'avx512vpopcntdq',
                      'pconfig', 'clwb', 'avx512f', 'clzero', 'pku', 'mmx', 'lwp',
                      'rdpid', 'xop', 'rdseed', 'waitpkg', 'movdir64b', 'sse4a',
                      'avx512bw', 'clflushopt', 'xsave', 'avx512vbmi2', '64bit',
                      'avx512vl', 'invpcid', 'avx512cd', 'avx', 'vaes', 'cx8', 'fma',
                      'rtm', 'bmi', 'enqcmd', 'rdrnd', 'mwaitx', 'sse4.1', 'sse4.2',
                      'avx2', 'fxsr', 'wbnoinvd', 'sse', 'lzcnt', 'pclmul', 'prefetchwt1',
                      'f16c', 'ssse3', 'sgx', 'shstk', 'cmov', 'avx512vbmi', 'avx512bf16',
                      'movbe', 'xsaveopt', 'avx512dq', 'adx', 'avx512pf', 'sse3'],

and now I receive

This bug happens as RBC is selecting system clang to compile C code. When the system clang version is greater than the one used by Numba/llvmlite, parts of the IR (i.e. new attributes) may not be recognized by the LLVM shipped with llvmlite.

This bug should be fixed in #520 and #521
