It's possible to short-circuit the clang -cc1 / -as invocation to run 
in-process with a minor code tweak to the driver (there was a patch on 
the list, but it's easy enough to do yourself if you take a look where 
the process is invoked).

There's no easy way to do that for the linker invocation at present, 
however, since it's a distinct executable. Fortunately there are few 
linker invocations compared to the former during a typical compilation.

It's likely we'll be investigating proper in-process compilation support 
in small steps over the next release cycle.
