When compiling using icecream, the whole input is one file fed from stdin,
so getBufferName() is "<stdin>", so get the filename from #line directives.

If the clang binary comes from a package which had been built before
any of our clang related sources were changed the last time, the timestamp
would be older and so there would be no rebuild. So do the stamp handling
the usual way, clang upgrades will work fine, downgrades will not, but
that's the same problem like with downgrading a library and its headers.
To somewhat mitigate the problem (Clang plugin doesn't get cleaned by
'make clean'), include the full Clang version (which includes SVN revision)
in config_clang.h and make all Clang plugin code include that, so
at least configure re-run will trigger a rebuild if necessary.

Check that only LO's files are processed, as there's no point otherwise.
Also warn about files in workdir/solver/builddir, as those are either
generated or copies. Try to automatically match include files from
solver to srcdir though, as that's where include files are usually
included from :(.
