This is not a 4.6 regression, though it may be a regression starting in 
some earlier release series.

The problem is Common options that aren't actually handled in opts.c.  The 
fix for now would be to add dummy cases for them to opts.c - the proper 
fix, once driver --help is done through .opt files, would be to mark -pie 
and -shared as Driver options (which they are) not Common ones.

Joseph, for 4.7, do you prefer this version

Or this one (or something else)?  Having driver display_help use *.opt stuff is
probably beyond stage4 material.

I suppose we should avoid the ICE for releases by simply turning the gcc_assert
into a gcc_checking_assert ...

Fixed on the trunk.  Not worth backporting I think.
