0cbcf92749 Use annotations on blocks
Previously, block_ty returned the type of the terminating
expression of the block (or nil if said expression was absent).
I changed check_expr to write the type of that expression into
the annotation for the block itself, so now block_ty can use the
block's annotation.

1a96e79fe0 Make _|_ unify with anything
The typechecker had a number of special cases for unifying types
with _|_ (as with checking if and alt). But, a value of type _|_
should be usable in any context, as such a value always diverges,
and will never be used by its immediate context. Changed unify
accordingly, removed special cases.

bad05e20a3 Improve nonexistent-module error message
The error message for (for example) "import vec;" without "use std;"
was "cyclic import", which was misleading because there were no
cycles. I changed it to "cyclic import or nonexistent module",
which doesn't break existing tests.

c9a8bdee2f Improve error message for ambiguous polymorphic types
If a type still contains free type variables after typechecking (for
example, as with "auto foo = []", the result was an assertion failure
in typeck. Made it a human-readable error message instead.

b620be9cd2 Typecheck @[] correctly
Previously, if you wrote
let @vec[int] foo = @[];

that would be a type error. That didn't seem right, so I changed
pushdown to unify the inner type in an unop application with the
argument type of the operator type.

a08a376d6e Make controlflow part of a function type
Change ty_fn to have a controlflow field. A 'controlflow' is
essentially a bit of data that says whether or not this function
never returns to the caller (if it never returns, that means it calls
"fail" or another "never-returns" function on every control path).

Also add syntax for annotating functions that never return:

fn foo() -> ! {
   fail;
}

for example. Functions marked with ! implicitly have a result type of
ty_bot, which is a new type that this commit also adds.
