29144c7932 Fix handling of let rhs that don't return 
In the case that a let rhs doesn't return and therefore the
bodies of the let are unreachable, the bodies need to be marked
as ignored for the optimizer.

In addition, don't attempt unboxed let optimization at all
if the return type is Nothing since it probably means some
body expressions have no type.

Closes GH issue #165

6512b52b1d Fix polymorphic recursion check for type aliases 
The old check was broken for cases with type constructors
with more than one type argument and was also too conservative
in some cases (e.g., when one cycle refers to another cycle of
 aliases in a non-recursive manner).

The new check is still conservative, but it allows more types
than before.

5cd5f772d6 Don't allow promises created with delay/name as (Promise T). 
Since these promises re-evaluate their bodies every time they
are forced, allowing them makes `force` not idempotent and not
safe to treat as a path.

This change is slightly backwards-incompatible, since programs
that previously passed `delay/name` promises across the typed
boundary will now fail at runtime. The alternative is also
incompatible: stop treating `force` as a path. Since `delay/name`
is quite obscure, this approach seems like the safer choice.

1842aaa2bd fixes for some tests 
The `identifier-binding` function is now senstive to the "macro
introduction" scope that's on an indentifier provided to a currently
expanding macro. Unit tests for TR need to use
`syntax-local-intorduce` to remove it, in the same way that `tc-setup`
already does.

Also, recognize a class expansion when it's wrapped with
`#%expression`, since `class` now expands that way sometimes.

609d6189e9 Improve typecheck for private field initializers 
This patch addresses two issues with `typed/racket/class`:

1. For multiple private fields declared with `define-values`, type
information does not propagate from the values produced by the
initialization expression to the declared fields. This breaks soundness
of private fields: A field can be annotated with a type that does not
contain the field's initial value.

This was resolved by keeping a table of temporary bindings introduced in
the expansion of the initializer along with their types. The field
setter's type is then checked against that of the corresponding
temporary.

2. The class body typechecker assumes that the `expr` of
a `define-values` clause will expand to a bare `(values vs ...)`.

This was resolved by generalizing the template for matching an expanded
`define-values` initializer and extracting the type information from the
`expr` instead of each element in `(vs ...)`.

c70910aaa0 Fix type restriction in values->tc-results 
Previously the restriction didn't account for traversing
the object type with the given path. This also relies on
the previous commit that adds subtyping on filters.

(because this change seems to introduce filters which
 only differ by an unrolling of a recursive type, but
 the old subtyping only worked for identical types)
