This commit adds support for template type-checking a pipe binding which
previously was not handled by the type-checking engine. In compatibility
mode, the arguments to transform() are not checked and the type returned
by a pipe is 'any'. In full type-checking mode, the transform() method's
type signature is used to check the pipe usage and infer the return type
of the pipe.
Testing strategy: TCB tests included.
