Summary: I needed it for debugging but, to my dismay, it was borked again. This time it was because `jbuilder` moved the object files to another directory since the last jbuilder update.

Summary:
Make the starvation checker enabled by default.
Add a deadlock issue type, distinct to starvation, which will be kept for UI thread starvation.
Add checks so that checker will do nothing on non-Java code.

Summary:
This simplifies the frontends and backends in most cases. Before this diff,
returning `void` could be modelled either with a `None` return, or a dummy
return variable with type `Tvoid`. Now it's always the latter.

Summary:
The abstract interpreter tried to handle exceptional control-flow by propagating the *pre* of a block that threw an exception rather than the *post*.
This was a half-measure that isn't correct when an exception-throwing instruction isn't in the middle of a block.
The handling of exceptions wasn't actually used anywhere and was leading to further hacks in `ProcCfg`, so let's get rid of it.

Summary:
We want instr-granular invariant maps so let's use the OneInstrPerNode CFG in the AI analyzers.
This requires specializing the TransferFunctions.
Keep using the normal CFG where we only need node-granular informations.

Summary:
When looking at large CFGs, at least in `xdot`, it's often difficult to find
the procedure you're looking for. Sorting the proc names puts them in
alphabetical order, which makes searching one procedure easier.

Summary:
Run with `SHELL = bash -e -u -o pipefail` to catch many kinds of failures. We
were silently failing during `make install` because of some missing escaping,
and the failure was hidden because it was happening inside a bash `for` loop.
This fixes the escaping issue and makes sure such issues will result in an
error as of now.
Also removes dangerous `find -exec` instances: `find` will `exit 0` event if
some commands failed.

Summary:
It renames `eval_locs` to `eval_arr` and we use it for getting array block values the given input expressions are pointing to. For example, when given a program variable `x` as an input, `eval_arr` returns array blocks that `x` is pointing to, on the other hand, `eval` returns an abstract location of `x`.

If an aggregate `a` has a field `f` whose type has a constructor (e.g., `std::string`), we translate creating a local aggregate `A { "hi" }` as `string(&(a.f), "hi")`.
