D59433 and D60501 changed the way UUIDs are computed from minidump files. This was done to synchronize the U(G)UID representation with the native tools of given platforms, but it created a mismatch between minidumps and breakpad files. This updates the breakpad algorithm to match the one found in minidumps, and also adds a couple of tests which should fail if these two ever get out of sync. Incidentally, this means that the module id in the breakpad files is almost identical to our notion of UUIDs, so the computation algorithm can be somewhat simplified. llvm-svn: 358500
