Summary:
This translates the construct `ObjCBridgedCastExpr` when the cast_kind is `OBC_BridgeTransfer`, or in syntax, the cast (`__bridge_transfer`).
This cast means that the object is passed from manual memory management to ARC, so one doesn't need to call `release` manually. It is important to model this to avoid false positives.
It translates it as a builtin that we then model in Pulse, the same way we modelled `CFBridgingRelease` which does the same thing.
The name of the builtin is `__free_cf` which is not ideal but I left it like that for compatibility with biabduction. We can change it once we remove this check from biabduction.

Summary:
Replace horrible hack with ok hack.
The main difficulty in implementing the disjunctive domain is to avoid
the quadratic time complexity of executing the same disjuncts over and
over again when going around loops:
First time around a loop, assuming for example a single disjunct `d`:
```
[d]
loop body
[d1' \/ d2']
```
Second time around the same loop: the new pre will be the join of the
posts of predecessor nodes, so `old_pre \/ post(loop,old_pre)`, i.e.
`d \/ d1' \/ d2'`. Now we need to execute `loop body` again
*without running the symbolic execution of `d` again* (and the time after
that we'll want to not execute `d`, `d1'`, or `d2'`).
Horrible hack (before): Disjuncts have a boolean "visited" attached
that does its best to keep track of whether a given disjunct is old or
new. When executing a single *instruction* look at the flag and skip the
state if it's old. Of course we have no way to know for sure so it turns
out it was often wrongly re-executing old disjuncts. This was also
producing the wrong results over even simple loops: only the last
iteration would make it outside the loop for some reason. Overall, the
semantics were pretty untractable and shady at best.
New hack (this diff): only run instructions of a given *node* on
disjuncts that are not physically equal to the "pre" ones already in the
invariant map for the current node.
This gives the correct result over simple loops and a nice performance
improvement in general (probably the old heuristic was hitting the
quadratic bad case more often).

Summary:
We translated the expression `CXXStdInitializerListExpr` naively in D3058895 as a call to
a skip function, with the hope that it would be translated better in the future. However, the naive means that we lose access to the initialized list/array because we are simply skipping it. So, even if we want to model the initializer properly, we have to deal with the skip specially.
This diff tries to solve this problem by removing the skip call whenever
possible. Instead, we translate the underlying array/list as a Load, so
that when it is passed to the constructor, we can pick it up.
For the following initialization:
``` std::vector<int*> vec = {nullptr};
```
Before, we translated it as
```
*&0$?%__sil_tmpSIL_materialize_temp__n$7[0]:int* const =null
n$8=_fun___infer_skip_function(&0$?%__sil_tmpSIL_materialize_temp__n$7:int* const [1*8] const )
n$9=_fun_std::vector<int*,std::allocator<int*>>::vector(&vec:std::vector<int*,std::allocator<int*>>*,n$8:std::initializer_list<int*>)
```
However, this means, `n$8` would be result of something skipped which we can't reason about. Instead, we just pass the underlying initialized array now, so we get the following translation:
```
*&0$?%__sil_tmpSIL_materialize_temp__n$7[0]:int* const =null
n$8=*&0$?%__sil_tmpSIL_materialize_temp__n$7:int* const [1*8] const

Computing sledge's equality relation and normalising terms is costly. We

condition lazily evaluated and only forcing it down to a value at two
critical points in the analysis:
1. Summary creation, to avoid storing unsatisfiable pre/posts that will have
to be needlessly executed by callers. This also saves us from having
to serialise the closures involved in the uncomputed form of lazy
values inside the pulse summaries.
2. Before reporting errors we check in the state is in fact satisfiable.
If not we just prune it away at that point.
This yields ~4x speedup on some targets.

Summary:
When encountering a constant, pulse creates an abstract value (a
variable) to represent it, and remembers that it's equal to it. The
problem is that pulse doesn't yet know how to deal with the fact that
some variables are going to be equal to each other.
This hacks around this issue in the case of constants, within the same
procedure, by remembering which constants have been assigned to which
place-holder variables, and serving those variables again when the same
constant is translated again.
Limitation: this doesn't work across procedure calls as the "constant
maps" are not saved in summaries.
Something to look out for: we don't want to make `if (p == NULL)` create
a path where `p` is invalid (we only make null invalid when we see an
assignment from 0, i.e. `p = NULL;`).

* redesign the abstract of multiple locations, like `Bottom` < `Unknown` < `Known` locations
I am doing them in one diff since applying only one of them showed bad results.
Background: `Unknown` was adopted for abstracting all unknown concrete locations, so we could avoid missing semantics of assignments to unknown locations. We tried to keep soundness. However, it brought some other problems related to precision and performance.
1. Sometimes especially when Inferbo failed to reason precise pointer values, `Unknown` may point to many other abstract locations.
2. At that time, value assignments to `*Unknown` makes the situation worse: many abstract locations are updated with imprecise values.
This problem harmed not only its precision, but also its performance since it introduced more location entries in the abstract memory.

Summary:
Simplifies the models story. The model jar is still needed to look up
