[patch, fortran] Implement FINDLOC

Sun Oct 21 17:37:00 GMT 2018

Hello world,

here is the implementation of FINDLOC.  This is another
step towards full F2008 compliance (we're not that far
away, actually, modulo a few bugs, of course).

This was quite a big piece of work, but at least I ended
up understanding a bit about trans-*.

Regression-tested.

OK for trunk?

Regards

	Thomas
