In debug mode, they are read from predefined files. In non-debug mode,
current analyzer results are dynamically obtained from Webkit SVN and
the latest previous result is read from the corresponding file.
Args:
debug: please refer to |options|.
test_group_file_location: please refer to |options|.
test_group_name: please refer to |options|.
result_directory_location: please refer to |options|.
Returns:
a tuple of the following:
prev_time: the previous time string that is compared against.
prev_analyzer_result_map: previous analyzer result map. Please refer to
layouttest_analyzer_helpers.AnalyzerResultMap.
analyzer_result_map: current analyzer result map. Please refer to
