14d85ca87a Make bind glue do an llvm tail call to the target. Closes #2. 
Now, llvm probably won't actually *emit* a tail call with the compiler
options and configuration we have, but this should punt it over to the
more general "do tail calls" bug.

0340f32748 Eliminate autoderef on binops and unary negation. 
Autoderef on binops is basically unused, kind of silly, and
complicates typechecking. There were only three instances of it in the
compiler and the test drivers, two of which were of the form "*foo =
foo + 1", which should be written as "*foo += 1" anyways.

c5c8258937 Rework check_expr substantially. 
The bulk of check_expr is now check_expr_with_unifier, which takes an
expected type and a unification function and will perform the
unification on the type it produces. check_expr calls
check_expr_with_unifier with a dummy unifier and a new function,
check_expr_with, takes an expected type and uses the simple unifier.

I think this generally makes thing cleaner, but the purpose for doing
this is to enable type inferred lambda-blocks to be useful by allowing
the argument types to be unified before the body of the lambda is
checked.

Michael Sullivan
67e361a940 Introduce a ty_infer ast node and use it instead of option::t[ty]. 
This actually basically makes things worse, since we get less nice
type system guarentees but it will make doing type inferred blocks a
fair deal less painful. I'm not /really/ happy about this...

1c786bcc82 Initialize all constraints to False 
Previously, typestate was initializing the init constraint for
a declared-but-not-initialized variable (like x in "let x;") to False,
but other constraints to Don't-know. This led to over-lenient results
when a variable was used before declaration (see the included test
case). Now, everything gets initialized to False in the prestate/poststate-
finding phase, and Don't-know should only be used in pre/postconditions.

This aspect of the algorithm really needs formalization (just on paper),
but for now, this closes #700

d7ee55bfd0 (Almost) Always unify a function tail expr with the function result type 
typeck::check_fn had an exception for the case where the tail expr
was compatible with type nil -- in that case, it doesn't unify the
tail expr's type with the enclosing function's result type. This
seems wrong to me. There are several test cases in Issue #719
that illustrate why. If the tail expr has type T, for some type
variable T that isn't resolved when this check happens, then T
never gets unified with anything, which is incorrect -- T should
be unified with the result type of the enclosing function. (The
bug was occurring because an unconstrained type variable is
compatible with type nil.)

Instead, I removed the check for type nil and added a check that
the function isn't an iterator -- if it's an iterator, I don't
check the tail expr's type against the function result type,
as that wouldn't make sense.

However, this broke two test cases, and after discussion with
brson, I understood that the purpose of the check was to allow
semicolons to be omitted in some cases. The whole thing seems
rather ad hoc. But I came up with a hacky compromise solution:
instead of checking whether the tailexpr type is *compatible*
with nil, we now just check whether it *is* nil. This also
necessitates calling resolve_type_vars_if_possible before
the check happens, which worries me. But, this fixes the bug
from Issue #719 without requiring changes to any test cases.

Closes #719 but I didn't try every variation -- so reopen the bug
if one of the variations still doesn't work.

2baaeab784 Implement the occurs check 
In the writeback phase, the typechecker now checks that it isn't
replacing a type variable T with a type that contains T. It
also does an occurs check in do_autoderef in order to avoid
getting into an infinite chain of derefs.

I'm a bit worried that there are more places where the occurs
check needs to happen where I'm not doing it now, though.

731797d075 In trans, don't assume both sides of a binop have the same type 
This was at least partially responsible for Issue 777.

    The only solution I can think of is for trans to just not generate
    code for a comparison if one or both sides has type _|_. Since
    that means evaluating that subexpression diverges, it should be ok
    to never do the comparison. Actually generating code for the
    comparison would trip an LLVM assertion failure.
