Merge cc1, cc1plus, etc?

[Mike Stump]

One way to get this done, would be to start with a small subset and 
work on it, get it done and in, and then expand.

I think this is desirable and doable and would provide a way to get 
your feet wet...

I'd start with one target, examine all the ways in which it goes 
through collect2, and then fold _that_ functionality into the driver 
(gcc.c) for that target get that in, then do another target, and then 
at the end, you can do AIX.  :-)

I think this subpart is non-controversial and desirable, though, it 
would have to go into a post 4.0 tree.

I don't see that a branch would be necessary for this sub-part.
