Driver: Objective-C should respect -fno-exceptions

Clang attempted to replicate a GCC bug: -fobjc-exceptions forces
-fexceptions to be enabled.  However, this has unintended effects and
other awkard side effects that Clang doesn't "correctly" ape (e.g. it's
impossible to turn off C++ exceptions in ObjC++ mode).

Instead, -f[no]objc-exceptions and -f[no]cxx-exceptions now have an
identical relationship with -f[no]exceptions.
