Issue Description:

C++ projects such as LLVM turn off exceptions and rtti support to reduce code size and enforce a restricted subset of C++.

-fno-exceptions -fno-rtti

The Swift Package Manager should support disabling C++ exceptions and RTTI on a per-target basis.

We may want to disallow using -fno-rtti without -fno-exceptions, since combining code built with -fno-rtti -fexceptions and code built with -frtti -fexceptions can cause ODR violations for the RTTI generated for exception types.
