ccc: Embrace destiny as a clang compiler driver.
This redoes the default mode that ccc runs in w.r.t. using clang. Now
ccc defaults to always using clang for any task clang can
handle. However, the following options exist to tweak this behavior:
-ccc-no-clang: Don't use clang at all for compilation (still used for
static analysis).
-ccc-no-clang-cxx: Don't use clang for C++ and Objective-C++ inputs.
-ccc-no-clang-cpp: Don't use clang as a preprocessor.
-ccc-clang-archs <archs>: If present, only use clang for the given
comma separated list of architectures. This only works on Darwin for
now.
Note that all -ccc options must be first on the command line.
