Construct exhaustiveness branches with condition, not branch, variable 
Previously we would construct the shapes of unions used in the pattern
tree for exhaustiveness checking using the type of the branch patterns,
rather than the type of the condition variable. Clearly we want to
always use the condition variable, otherwise some branches will be
seen as exhaustive, when they are not!

To do this, we now index into the condition variable while refying the
patterns to build the tree for exhaustiveness checking.

Lose rigidity of annotated optional fields before generalization 
We have this idea of "rigid optional" fields to annotate record fields
that must necessarily be optional. That avoids the admission of programs
we cannot faithfully compile, like

```
f : {a: Str, b ? U64}
f = {a: "b", b: 1}
```

We want to lose the rigidity restriction when a generalized symbol is
used as at a specialized site; for example it should be possible to call
`f : {x ? Str} -> {}` with both `{}` and `{x : Str}`, neither of which
have a rigidly optional field unless they were to be annotated.

Prior to this commit we would loosen the rigidity restriction upon
specialization of a generalized type at a use site. However, what we
really want to do is apply the loosening during calculation of
generalization. The reason is that otherwise, we must make types that
would be ground (like `{x ? Str} -> {}`) generalized just for the sake
of the optional field annotation. But since the rigidity constraint is
irrelevant after an annotated body has been checked, we can loosen the
rigidity restriction then, which conveniently happens to coincide with
the generalization calculation.

Support captures between mutually recursive closures 2022-08-13 10:25:18 -07:00

Fixup transient closure captures during canonicalization 
Closure captures can be transient, but previously, we did not handle
that correctly. For example, in

```
x = ""
inner = \{} -> x
outer = \{} -> inner {}
```

`outer` captures `inner`, but `inner` captures `x`, and in the body of
`outer`, we would not construct the closure data for `inner` correctly
before calling it.

There are a couple ways around this.

1. Update mono to do something when we are passed the captured
   environment of a closure, rather than attempting to construct a
   call-by-name's captured environment before callign it.
2. Fix-up closures during canonicalization to remove captured closures
   that themselves capture, and replace them with their captures.

This patch does (2), since (1) is much more involved and is not likely
to bring a lot of wins. In general I think it's reasonable to expect
captured environments, even if transient, to be fairly shallow, so I
don't think this will produce very large closure environments.
