Summary: Calling any non-libc builtin function in the expression command currently just causes Clang to state that the function is not known. The reason for this is that we actually never initialize the list of builtin functions in the Builtin::Context. This patch just calls the initializer for the builtins in the preprocessor. Also adds some tests for the new builtins. It also gets rid of the extra list of builtins in the ClangExpressionParser, as we can just reuse the existing list in the Preprocessor for the ASTContext. Having just one list of builtins around is also closer to the standard Clang behavior.
