565ea068ca Add type parameters when checking wildcard patterns
For some reason, wildcard patterns were never getting type parameter
substitutions attached. This would cause an assertion failure when
checking a wildcard pattern that matches against a tag with
polymorphic type (not sure why this didn't come up before). Fixed it.
(The diff and test case may be easier to understand than this note
:P)

Closes #1503.

efb9df1ebd Make driver::session::session no longer an object
Rather, it is now a struct where properties like opts are accessed
directly, and the error-reporting methods are part of a static impl
(with the same name as the type).

08abf8d37f Support explicit discriminant numbers on tag variants.
Addresses issue #1393.

For now disallow disr. values unless all variants use nullary
contractors (i.e. "enum-like").

Disr. values are now encoded in the crate metadata, but only when it
will differ from the inferred value based on the order.

7c7559edaf Disallow variable names that shadow tags in scope
Now, if you have a tag named "foo", a variable declaration like
"let foo..." is illegal. This change makes it possible to eliminate
the '.' after a nullary tag pattern in an alt (but I'll be doing
that in a future commit) -- as now it's always obvious whether a
name refers to a tag or a new declared variable.

resolve implements this change -- all the other changes are just to
get rid of existing code that declares variables that shadow tag
names.
