This is ready for another look @dblaikie -- added some failure tests that were easy to catch (not found, no instrumentation map) and provided some sample binaries to use instead of creating one on the fly (as it seemed harder to generate a final linked executable from a .ll).

If you have ideas about how to make the sequence:

  llc ...; <link the .o into a final binary> ;  llvm-xray extract <final binary>

work in a `.ll` test, I'd be very interested to try.
