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.

The solver for interpreted functions relies on the solution
substitutions containing mappings from variables to interpreted
applications, and never in the reverse. When solving equations
involving polynomials, this constraint is specifically
established. But for equalities involving only monomials, it could
happen that e.g. `x` was chosen as the representative of `a × b`,
which violates this constraint.

Generate output on stderr containing lines such as:
```

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:
```

Summary: The flags `--biabduction-fallback-model-alloc-pattern` and `--biabduction-fallback-model-free-pattern` were unused because we removed the models from .inferconfig a while ago because of too many false positives. We are implementing a better memory leak check based on Pulse, and are adding the similar flags `--pulse-model-alloc-pattern` and `--pulse-model-free-pattern`.

Instead of having to remember to update both the inferbo and the concrete

The "interface" modules define short forms for the internals of pulse

of code(!) and is now in PulseInterproc.ml.

NOTE 2: As you can see from the test payload (see ModePromotions.java),
the precise calculation is not working as expected. This is due to a bug
