I've committed a slightly reworked version of JeanHeyd's
<source_location> patch (see attached). Jakub has improved the
built-in so all the commented out tests work now. There's one more
compiler patch coming to use __PRETTY_FUNCTION__ for the function
name, so I'll tweak the new tests after than has gone in.

Tested powerpc64le-linux, committed to trunk.

Thanks, JeanHeyd!
