    oe-build-perf-test: pre-check Git repo when using --commit-results
    
    Do a pre-check on the path that is specified with --commit-results
    before running any tests. The script will create and/or initialize a
    fresh Git repository if the given directory does not exist or if it is
    an empty directory. It fails if it finds a non-empty directory that is
    not a Git repository.
