[PATCH C++] - SD-6 Implementation Part 4 - Test suite.

Greetings,
I am finally getting back to my SD-6 C++ features test work.
This adds front end and preprocessor tests for the language feature tests and __has_include.
I am still working on the fifth and last in this series to add __had_cpp_attribute but these first four patches add a very useful subset of the SD-6 feature testing.
Bootstrapped and tested under x86_64-linux.
OK?
Ed
