- This is designed to make it obvious that %clang_cc1 is a "test variable"
which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
can be useful to redefine what gets run as 'clang -cc1' (for example, to set
a default target).

- Support noreturn on function-typed variables.
- Extend isFunctionOrMethod to return true for K&R functions and
provide hasFunctionProto to check if a decl has information about
its arguments. This code needs some serious cleaning, but works.
- Add/improve test cases for noreturn and unused.
