This avoids constraint explosions in some cases, notably when working
with polydots and plain variable arity functions at the same time.
However, this also weakens inference a bit (breaks it for
unholy-terror and related tests), but not in a way that affects any
practical use cases that I know of.

subtyping of value types easier.
However, this means that base types can't be marshaled as before,
since these predicates can't be marshaled. Instead, we now marshal
base types as identifiers that refer to their base type object.

- fields now represented by fld struct.
- mutability on per-field basis
- accessors are per field
This fixes lots of existing bugs, allows future #:mutable on fields.
original commit: c01b2397796cce0ade2ed7515ffe33c9eb338c4f
- generated only in the case where we have two ListDots or two ValuesDots
- or when -> with the same bound, and fixed argument lengts are identical
- currently errors if there are any 'fixed' portions
original commit: 034b22d01401bba31f700dd5cb38fcf731ed64be
- add convenience function for generating substitutions
- give trivial substitution for unreferenced index variables

This doesn't fully work, in that more test cases are broken. However,
this is mostly due to questionable inference rules in the past, and
so fixing these errors should lead to a more correct inference algorithm.
(i.e. we need to handle things like (List X ... a) (List Y .. b),
where a and b are not the same bound. We'd started this work before,
but never actually gone through with it, since smashing regular and
dotted type variables into the same environment meant some things
magically worked when they possibly shouldn't have.)

with subsequent adaptation of (planet cce/scheme) to collects/unstable.
These bindings are temporary, and will be replaced in the adaptation.
