Make ast::visit only descend into types when necessary

If visit_ty is not overridden, it uses a stub function which does not
descend into types.

Fix bad interaction between last-use finding and references
...
The last-use pass now takes input from the alias pass to not mark things
as last uses that are still accessed through a reference.

Update stdlib, compiler, and tests to new kind system
...
This involved adding 'copy' to more generics than I hoped, but an
experiment with making it implicit showed that that way lies madness --
unless enforced, you will not remember to mark functions that don't
copy as not requiring copyable kind.

Make tag, resource and object constructors take their arguments by copy
...
Doing something like some([1, 2, 3]) will now no longer create a temporary
copy of the vector. It will also be easier for the kind checker to see that
putting a resource into a data-structure constructor is safe.

Add a pass-by-copy parameter passing convention
...
This is intended to solve the problem of how to pass arguments to
constructor functions -- you want to move in rvalues, but not have to
explicitly copy stuff that is not an rvalue. The by-copy passing
convention will ensure the callee gets its own copy of the value. For
rvalues, it'll just pass off the value. For lvalues, it'll make a
copy.

Preparation for kind system overhaul
...
This goes before a snapshot, so that subsequenct patches can make the
transition without breaking the build. Disables kind checking pass, makes
parser accept both new and old-style kind annotation.
