Buck reads the version on stderr or, very recently, from either stdout or stderr.
This makes infer output the version of stderr when called from Buck or invoked as javac, and on stdout otherwise.

One day `-a infer` will alias `-a checkers` so for now create another, more
explicit analyzer name that can be used to migrate progressively. For instance,
after this commit what should continue to use `-a biabduction` can change to
that, so that when `-a infer` becomes an alias to `-a checkers` it can keep
working.

Also extend the catching of "Unimplemented" and other errors to `translate_one_decl` as it was useful to debug this issue. In particular, reraise all exceptions and log some additional context when doing so.

Summary:
`reraise` was error-prone when one forgot to save the backtrace between where the exception is caught and where it is reraised.
If any exception was raised (even caught) in between, the printed backtrace would be the one of the last exception thrown and it would be very confusing.
This diff kills `reraise` and introduces `reraise_after exn ~f` and `reraise_if exn ~f` to be used right after catching the exception.
Also turned some of them to the common pattern `try_finally ~f ~finally`.

Summary:
Since D5381239, infer is careful not to delete directories that do not "look
like" results directories on startup, in case the user passed, eg, `-o /`.
In our repo, lots of results dir are created by build/test of infer, and when
the version of infer changes and the expected contents of results directories
change then it might start refusing to delete the results directories created
with another version of infer.
Add an option to force infer to delete the results directory no matter how
dodgy it looks, and use it in our repo by adding the option in every
.inferconfig.

Summary:
We need to make sure that destructors of virtual base classes are called only once. Similarly to what clang does, we have two destructors for a class: a destructor wrapper and an inner destructor.
Destructor wrapper is called from outside, i.e., when variables go out of scope or when destructors of fields are being called.
Destructor wrappers have calls to inner destructors of all virtual base classes in the inheritance as their bodies.
Inner destructors have destructor bodies and calls to destructor wrappers of fields and inner destructors of non-virtual base classes.

Summary:
The clang frontend uses `assert false` for unimplemented features that should
abort method translations, as well as for genuine internal errors.
Distinguishing between the two, we can fail hard on the latter and not the
former.
1. This introduces a new exception `Unimplemented` that is used instead of `assert false` where appropriate.
2. Changed some other cases into `die ...` (when there's an error message to display)
3. Wherever a path in the code that we assumed to be unreachable was observed reachable, we now raise `IncorrectAssumption`. These should be fixed, but the fixes are not obvious.

Summary:
"Running as clang" was its own infer subcommand. That's not terribly good
because it makes it hard to specify another subcommand, and in particular it
broke the `compile` subcommand in some integrations because "running as clang"
would always do capture. The cmake tests required to run with `--keep-going`
because of this.
Instead of having its own fake subcommand, simply add a new boolean in the
config for "infer runs as clang", as we do for javac already (used in the mvn
integration).
Also make logging of the environment better.
