This is a proof-of-concept patch. It does not add the tail policy
argument to all the builtins/intrinsics. This patch uses vadd as an
example to add the tail policy argument.

I added several new classes. There is no need to add these classes in
the target description. I do so just to limit the modification to vadd
only.
