Tells the user which missing keywords were mandatory and
which were optional (which is useful if, e.g., the expected type
says mandatory but the function had it optional).
original commit: 8b53d32f5231f94677e1088b940e92a71ed1e311
In particular, allow the optional kws to be left out in the
expected type (a function type with fewer optional kws is
a supertype).

Override the `define/foo` forms for racket/class to
allow type annotations and to use TR's keyword property.
original commit: 4aa438937ac315d0b64bccffa86663a97cadde6f
This checks that the given lambda has the right keywords
wrt to the expected type. Doing this should avoid the bad
arity errors that result from the kw protocol encoding.

I have no idea whether the change is generally right, but it allows
the build to complete and DrRacket to start.

This changes Filters to have a Path as a subcomponent instead of having
the list of Path-Elems and name-ref/c separately. This is part of the
rework to have better object support.

Before that, ((inst make-vector Natural) 10) would return a (Vectorof
Integer) which is bad.
Thanks to Alexander Knauth for the suggestion!

This removes the need for the cache of type variables for instantiating
dotted variables, because we instantiate the uses at once.

If code is unreachable then looking up any variable should return
Bottom. But implementing checking unreachable code that way is not that
useful.

There ought to be a way to improve the type of `apply-pattern-substitute`,
but we haven't found it yet.

Also fix TR `send` for multiple/any values as receiver
Now emits a real type error instead of crashing with
an internal match error.

Use new merge-tc-results as well.
This revealed some buggy tests as well which are also fixed.

(T @ x) => (! S @ x) when their intersection is empty.
Rearrange how we look through filters in -and so this rule applies more.

The non-productive type check in type parsing and in type
alias setup should produce the same failure messages.
