Alex, the patch is ok for trunk and 4.7 branch.  That said, with similar code
just appearing not in call site parameter, but in a .debug_loc section we'd ICE
anyway, as .debug_loc has a hard limit of 64K, and furthermore we should do a
better job on this testcase, instead of creating such a huge expression which
keeps recomputing the same values again and again introduce some kind of
temporaries in the expression, if some expression occurs more than a few times,
compute it into a temporary first (on the DWARF stack) and then just pick it
when needed, drop at the end.
