Implement basic __is_trivial type-trait support, enough to close PR9472.
This introduces a few APIs on the AST to bundle up the standard-based
logic so that programmatic clients have access to exactly the same
behavior.

There is only one serious FIXME here: checking for non-trivial move
constructors and move assignment operators. Those bits need to be added
to the declaration and accessors provided.

This implementation should be enough for the uses of __is_trivial in
libstdc++ 4.6's C++98 library implementation.

Ideas for more thorough test cases or any edge cases missing would be
appreciated. =D
