A number of test cases were failing on big-endian systems simply due to byte order assumptions in the tests themselves, and no underlying bug in LLDB. These two test cases: tools/lldb-server/lldbgdbserverutils.py python_api/process/TestProcessAPI.py actually check for big-endian target byte order, but contain Python errors in the corresponding code paths. These test cases: functionalities/data-formatter/data-formatter-python-synth/TestDataFormatterPythonSynth.py functionalities/data-formatter/data-formatter-smart-array/TestDataFormatterSmartArray.py functionalities/data-formatter/synthcapping/TestSyntheticCapping.py lang/cpp/frame-var-anon-unions/TestFrameVariableAnonymousUnions.py python_api/sbdata/TestSBData.py (first change) could be fixed to check for big-endian target byte order and update the expected result strings accordingly. For the two synthetic tests, I've also updated the source to make sure the fake_a value is always nonzero on both big- and little-endian platforms. These test case: python_api/sbdata/TestSBData.py (second change) functionalities/memory/cache/TestMemoryCache.py simply accessed memory with the wrong size, which wasn't noticed on LE but fails on BE.
