Summary: Now that we have the kind of lock stored (global/class obj/path rooted at parameter), use it for comparison/equality, while ignoring the root variable of the access path, which is only used for printing.

Identifying and separating one of the monomials in a polynomial, and
solving an equality for it, is much more dependent on the

Summary:
The exposed constructors for Memory and Concat Terms are only used in
a very special idiom: to construct an equality between a single Memory
chunk and the Concat of multiple Memory chunks. This diff specializes
and simplifies by exposing a Term.eq_concat constructor for this
idiom, and removes the underlying Term.memory and Term.concat
constructors.

Trace.infok is like Trace.info but accepts a polymorphic printf
continuation instead of directly taking a format string and its

Summary:
As part of enabling substitution of arguments into lock names in summaries, and potentially changing the equality relation over locks (so that we can eventually make equal `x.f.g` and `this.f.g` for example), the lock type needs to be elaborated so that the root of an access path is classified into:
- global variables are clearly separated from all other classes (invariant to substitution)
- class objects are also separate (also invariant, but identified by type)
- all other parameters remember their positional index (so that substitution becomes easier)
For now the comparison/equality is kept identical, so as to make easy CI comparisons.

Summary:
Now that they are uncurried, congruence closure does not need the
order of subterms to be preserved. Sorting them reduces redundancy in
case the same equality in different orders is encountered, and
improved printing.

Summary:
Equality.classes was assuming a simpler representation, and was
incomplete as a result.
The 'representative' map is not kept in a normalized form, where
subterms are necessarily representatives. Therefore, applying the
representative map to subterms of terms in a class can reveal new
elements of the class. This mirrors how the `lookup` function in
`normalize` works.

Summary:
Demonstrate that the per-file type environments don't prevent
the deadlock report here. The fear was that when the analyser
tries to locate the methods of the endpoint class, it might fail to
do so because the types might be stored in different type
environments (per file).
