Includes a few tweaks to Value.copyOf(a) (make it a no-op for a self-copy) and new pattern hack "___" (3 underscores) is like ellipsis, except the replacement doesn't need to have matching ellipsis/underscores. Moved the arg-length check in generated pattern-matching code BEFORE the args are probed, because not all instances of variable length OpFoo will have all the args mentioned in some rule for OpFoo, and when that happens, the compiler panics without the early check.
