Summary:
Change the implementation of `Equality.Subst.compose` to preserve
physical equality if the result is `Subst.equal` to the first
argument.

Summary:
Currently there is an implicit assumption in Sh.simplify that
variables do not occur free in an equality relation which makes no
constraint on their values. This diff adds a step to formula
simplification that explicitly removes eliminated existentials from
equality relations.

Summary:
Generate output on stderr containing lines such as:
```
solve_for_vars time: 0.105 ms 0.871 ms 79 calls
```
which indicates that the current maximal time of a single
`solve_for_vars` query is `0.105 ms` and so far the total time spent in
`solve_for_vars` over `79` queries is `0.871 ms`.
At program exit, there is also a line for each timer indicating the
max query time and final accumulated duration and number of queries:
```
solve_for_vars time: 0.173 ms 17.242 ms 1108 calls
```
Additionally, replay sexp are dumped interactively. A query exceeding
1 sec is dumped, then one exceeding 2 sec, then 4 sec, etc.

Summary:
This diff adds wrappers for Equality entry points that augment
exceptions escaping out of Equality with an sexp that can be given
back to Equality.replay in order to reexecute the function call that
failed.
A (bogus) example could be raising:
```
((Failure "domains intersect: ((u8) %x_5)")
(And_eq () (Ap1 (Unsigned (bits 8)) (Var (id 5) (name x)))
(Var (id 6) (name y))
((xs ()) (sat true)
(rep (((Var (id 6) (name y)) (Var (id 5) (name x))))))))
```
and then calling `Equality.replay {|(And_eq ...)|}`.

Summary:
Work on the containers revealed that 1b8746d21 was premature, and this
diff is in part a revert of that. The objectives for the global
namespace are:
- self-consistent as much as possible
- rich data type operations
- does not require maintaining lots of tedious library wrapping code
- has Marshalable containers
- has containers with functorial interfaces
For these aims, it's best to stick with Core. Base isn't enough to
define functorial interfaces for collections (without a lot of tedious
wrapping code to keep in sync manually), and since a few modules not
in Core_kernel are needed anyhow.

Summary:
This diff defines Map as a functorover the underlying implementation
of Core.Map. This results in map values that are just trees, with no
comparison function closures, and with the same interface (almost) and
underlying data structure implementation as Core.Map.

The term "vector" evokes expectations of being automatically growable,

Summary:
The base containers have inconvenient interfaces due to lacking
support for functors, which also leads to the representation of values
of containers including closures for the comparison functions. This
causes problems when `Marshal`ing these values.
This diff is one step toward not using the base containers.
