Summary:
This diff preserves values of offset and index separately, rather than
one value of their addition, because premature addition results in
imprecise FPs by the limited expressiveness of the domain.

Summary:
It avoids checking integer overflow when it definitely cannot happen.
For example, it does not check integer overflow of addition when one
of parameters is a negative number, or underflow of subtraction when
its first parameter is a positive number.

Summary: This diff changes pp of binary operation condition in order to avoid a `make test` failure. For the same `uint64_t` type, it is translated to `unsigned long long` in 64bit mac, but `unsigned long` in 64bit linux, which made a `make test` failure.

Make distinct reports on strict mode violations.
For now, restrict to direct violations (UI threads calls transitively a violating method).

Summary: Before this diff, the analysis would only lookup the attributes with the classname appearing in the instruction. However, it would fail to find those attributes for inherited and not overridden methods. With this diff, the attributes are now searched recursively in the super classes.

Summary:
Keep `--analyzer` around for now for integrations that depend on it.
Also deprecate the `--infer-blacklist-path-regex`,
`--checkers-blacklist-path-regex`, etc. in favour of
`--report-blacklist-path-regex` which more accurately represents what these do
as of now.
Rely on the current subcommand instead of the analyzer where needed, as most of
the code already does.

Summary:
Goal of the stack: deprecate the `--analyzer` option in favour of turning
individual features on and off. This option is a mess: some of the options are
now subcommands (compile, capture), others are aliases (infer and checkers),
and they can all be replicated using some straightforward combination of other
options.
This diff: stop using `--analyzer` in tests. It's mostly `checkers` everywhere,
which is already the default. `linters` becomes `--no-capture --linters-only`.
`infer` is supposed to be `checkers` already. `crashcontext` is
`--crashcontext-only`.

Summary: It is common on Android code to recycle the `View` object by nullifying them in the `onDestroy()` or `onDestroyView()` methods. In this case, the outer `Fragment` object structure is preserve while the inner `View` object are set to null for the garbage collect to release the memory. However, if the fields are only set to `null` in the `onDestroy*()` methods, those fields cannot be `null` during the active lifecycle of the `Fragment`, so it is not necessary to annotate those fields with `Nullable`.

Summary:
First step in writing an analyzer that is meant to run only on Android core library implementation.
This will, when finished, compute the library entrypoints that may lead to a strict mode violation.
The normal analyzer will use those to statically flag strict mode violations in app code.
Strict Mode is an Android debug mode, where doing certain things (like disk read/write or network activity) on the UI thread will raise an exception. We want to statically catch these, as well as indirect versions (the UI thread takes a lock and another thread holding that lock calls a method that would be a strict mode violation).
