    This commit adds support for storing hashes of the test binaries as a
    new sample type. The idea is that when the hash function of the same
    test is the same as on a previous run, the analyses can assume that
    the binary didn't change in a meaningful way.

    None of the analyses in LNT have been adapted yet to take advantage of
    this extra information.

    The hash value is stored as a new sample type.  Since the hash value
    in many cases should not be handled the same as other sample types,
    like execution time or compilation time, a distinction needs to be
    made. This patch changes terminology in LNT and calls sample types
    that have a meaningful order, like execution time and compilation
    time, "metic fields". The hash function of a binary - as one hash
    value cannot be said to be "better" than another hash value - is not
    considered a "metric field".
