[PATCH] clang: forward -no-integrated-as from the driver

Assuming we want something like this (I don't think we do), I would
still ask for some changes in the patch:

* Needs a testcase.
* Using an explicit "-S -fintegrated-as" should still pass
-integrated-as to -cc1. That is, the driver should only have different
*defaults* for -c and -S.

Cheers,
