There are some more complex cases (_Complex and structs)
that I'm still working on.

unused loads or bitcasts.

If the instruction has no users, it is also not only used by debug info 
and should not be deleted.

 - Support things like telling which -ffoo -fno-foo option won, and
   forwarding all arguments matching a certain set of options to the
   tool.

argument translation.

Also, stub out clang tool implementation a bit more.

handled by driver. 
 - This is not very precise, we use it to drive the "forward-to-gcc"
   predicate, when trying to talk to a generic gcc tool.

 - Slightly better than what ccc was doing, and should be good
   enough. Platforms which want a robust driver should implement a
   proper tool chain.

and expanding a bit convert (PR3711).  In both cases, we extract the
valid part of the widen vector and then do the conversion.
