Summary:
This diff addresses collection adds in loop. For example,
```
ArrayList<...> a = new ArrayList<>();
for (int i = 0; i < size; i++) {
a.add(...);
}
// we want to know the size of `a` here!
```
This is a common pattern on initializing a collection in Java.
How we did: Instead of adopting general (but complicated) solutions such as relational domain, we
extended the current alias domain of inferbo, to be able to handle this specific case:
* An array `a` should have size 0, at the entry of the loop.
* The iterating variable `i` should start with 0.
* `add` should be called once inside the loop.

Summary:
In D17156724, we forked nullsafe tests, which was a strategy to
introduce nullsafe-gradual mode back then.
The reason was "gradual" mode is a pretty big change in a way Infer
handles annotations, so we wanted to tests both scenarios: gradual and
non-gradual mode.
The plan was to deprecate "non-gradual" tests at some point, hence we
decided to go with duplication.
Now we have a better approach to ensure "gradual" features are well
covered. The approach is the following.
1. [Mostly finished] Improve existings tests so that they cover negative and positive
cases. With this, we can safely add something like
--non-annotated-default UNKNOWN_NULLABILITY to the test config and be sure tests still make
sense (i.e. don't pass simply because annotations don't make sense
anymore)
2. [In progress]. Refactor nullsafe code so that instead of using of Annot.ml everywhere we use a special abstraction telling if the class is annotated with Nullable, Nonnull, or not annotated. With this change, we essenstially have a single place we need to test, which removes the need to have 2 pair of tests for each feature.
3. [To be done]. Introduce Uknown nullability and add small number of tests specifically
for that feature (together with existing tests).
NOTE: I did not rename `nullsafe-default` back to `nullsafe` to not
pollute blame without need.

This diff is dealing with FieldNotNullable:

- modify the tests so they comply with the standards below
--Motivation--
Gradual mode we are going to introduce is an invasive change in how Infer
treats nullability semantics.
In order to make the change in a controllable way, we need the tests to comply with the
following standards and conventions.
1. For each code peace where we expect a bug to happen, the there should be
corresponding (minimally different from above) peace of code where we expect a bug to NOT happen. (This is to ensure bug is happening for exact reason we think it is happening).
2. Conversely: for each peace of code where we expect a bug to be NOT
present, there shuold be a peace of code where the bug IS happening.
(Otherwise there can be too many reasons for a bug NOT to happen).
3. Convention: end corresponding methods IsOK and IsBUG correspondingly.
4. Keep code examples as small as possible.

Summary:
In next diff, we are going to introduce a new mode of nullsafe
(gradual). For testing, we are going to employ the strategy used by jvillard
for Pulse.
In this diff we split tests into two subfolders, one for the default and one for the gradual
mode.
We are planning to make the gradual mode default eventually. For that, most
new features will make sense for gradual mode, and we will mostly evolve
tests for that mode.
As for 'default' mode, we need to preserve tests mostly to ensure we don't introduce
regressions.
Occasionally, we might make changes that make sense for both modes, in
this (expected relatively rare) cases we will make changes to both set
of tests.
An alternative strategy would be to have two sets of issues.exp files,
one for gradual and one for default mode. This has an advantage of each
java file to be always tested twice, but disadvantage is that it will be
harder to write meaningful test code so that it makes sense for both
modes simultaneously.

Present, which means that it is safe to call get().
We don't plan to support `Present` annotation for optional types in the
near future.
Support of `Present` annotation requires extra levels of abstraction
that make the changing the behavior and introducing new features harder.
A lot of checks for nullability are written in generic way so they also
check for presense.
Getting rid of that will allow us to simplify our
work for introducing new semantics for nullsafe.

`nullsafe` currently allows the following:
```
public void Nonnull Object willBeOK() { return null; }
```
But disallows the following:
```
public void Object willBeAnIssue() { return null; }
```
This was a deliberate choice made back in 2014.
The motivation was to provide a way to tell the checker "I know it can not be null, trust me".
A huge problem with that approach is that it is extremely non-intuitive and surprising, and contradicts with pretty much everything when Nonnull or similar annotations are used in external world.
This is not the way how checkers should be supressed.
We do provide 2 options to express this intention, namely `assertNotNull` and `assumeNotNull` would do the thing.
This is a much better approach for additional reason: assertNotNull is
granular and applies only to the exact expression that is under
question. In contrast, suppressing the check on the whole function level
make any modifications of a function dangerous.

Summary:
Change the logic of the annotation reachability checker in the following
ways:
1. Sanitizers take priority over sinks, i.e. a procedure that is both a
sink and a sanitizer is not a sink. This changes the existing tests
that seemed to assume the opposite. However I think that way is more
useful and goes better with the fact that sanitizers are specified as
"overrides".
2. When applying a summary, check again that we are not in a sanitizer
for the corresponding sink.
Without (2) this there was a subtle bug when several rules were
specified. For example, if `sink_wrapper()` wraps `sink()` for a rule
`R` then the summary of `sink_wrapper()` will be: `R-sink : call to sink()`.
Then, suppose `sanitizer()` calls `sink_wrapper()` and `sanitizer()` is
a sanitizer for `R` but not for another rule `R'`. The previous code
would add the call to `sink()` to the summary of `sanitizer()` because
it's not a sanitizer for `R'`, even though `sink()` is not a sink for
`R'`!
The current code will re-apply the rules correctly so that sinks are
matched only against the right sanitizers.

The genrule-capture integration with Java relies on a buck config flag `infer.infer_bin=<path to infer>` (see test changes in `DEFS` below).
In a CI environment where the infer binary is checked out under a random directory, this means that the buck genrule is keyed by a random string (the path to infer), and this defeats caching.
Switch to the following contract: the genrule target does not expect a config flag at all. Instead it runs whichever `infer` binary is in the path. To make sure the binary is the same one with the originator, the capture integration runs buck under a modified `PATH` where the originator `infer` is sure to be the first matching entry.
NB cache invalidation is still OK because we rely on `infer.version` buck config flag, which will be hashed into the rulekey.

Summary:
Treat `MainThread` and `WorkerThread` annotations.
Fix wrong test (`AnyThread` cannot call a UI-only method, because it can be called by ANY thread ;) ) See https://developer.android.com/reference/android/support/annotation/AnyThread
Clean up the code a bit.

Summary: There were FNs caused by only looking for the immediate predecessors when we were checking the pattern. This diff heuristically chases 4 more predecessors to reduce the number of FNs.

Summary:
Replaced by pulse. `--ownership` is now a deprecated form of `--pulse`.
The ownership checker is starting to give wrong answers due to changes in the
clang frontend, so it's better to remove it in favour of pulse.

So it turns out we need to translate even more cases. Pulse had a FP

Summary:
This is needed to test some functionality in the next diff. Only one
test changes (no longer a FN), which is now documented. Also, stop
including the "header models" meant for biabduction!
Maybe one day we'll need to have several test modes for different C++
versions. Seems overkill for now, so let's wait until we see some actual
issues (eg FPs) that manifest in one version but not the other.

Summary:
Sometimes the post of a function call has attributes on addresses that
were mentioned in the pre but are no longer reachable in the post. We
don't want to forget these, see added test.
