Summary:
This issue was spotted in the wild. There may be more of those, unfortunately it's hard to predict
More general problem is that types in infer frontend diverge from clang's types for DerivedToBase cast.
Then, infer uses types from clang anyway and that confuses backend. Getting it always right is very hard

Summary:
Improve type of `Fieldname.t` in `Clang` variant - make it store qualified classname and method name.
Based on those changes, fix matching in `Errdesc` to use `QualifiedCppName.Match` instead of string comparisons

Summary:
Split Fieldname.t into `Java` and `Clang`. Each of them have different naming conventions and this way it's easier to differentiate between them.
Make `Java` variant store string instead of mangled since mangled part was always empty
Changes to `Clang` variant are coming in the next diff

Reorganize by using a top-level iteration over the access map and using a helper function for updating the caller accesses.

Sometimes building the models segfaults mysteriously. I've observed in the

Summary:
All tests were redirecting `stderr` into duplicates.txt which made it much harder to see other error messages in stderr (such as uncaught exceptions).
To mitigate it, write duplicates to separate file and don't redirect `stderr` to another file.

Summary:
One limitation of Eradicate is that certain nullability patterns are not expressible using simply the `Nullable` annotation.
One such pattern is using the knowledge that a function returns null when passed null, but returns an object otherwise.
The annotation `PropagatesNullable` is a variant of `Nullable` applied to parameters when their value propagates to the return value.
A method annotated
```
B m(PropagatesNullable A x) { return x == null ? x : B(x); }
```
indicates that `m` returns null if `x` is null, or an object of class `B` if the argument is not null.
Examples with multiple parameters are in the test cases.
This diff builds some infrastructure for annotation transformers: the example above represents the identity function on nullability annotations.

Before, `trace_of_pname` only grabbed unprotected writes from the summary, so the traces ending in an unprotected read were truncated.

Summary:
Two issues in the previous code:
1. We'd just tack on `#compilation-database` so if there already are `#flavors`
in a Buck target then we get a malformed `#flavors#compilation-database`
instead of `#flavors,compilation-database`. There's already code to deal
with that for other flavors (`#infer-capture-all`), so extend and reuse that.
2. The code didn't work if there are spaces in target names (sigh). Harden the
code a bit so that it works. Unfortunately Buck doesn't escape spaces at all
in its `buck targets --show-output` output, so the parsing still relies on
there being no spaces in flavors to work correctly. Sample output:
```
$ buck targets --show-full-output //clang_compilation_database:Hel\ lo#compilation-database
Not using buckd because watchman isn't installed.

//clang_compilation_database:Hel lo#compilation-database /home/jul/infer/infer/tests/build_systems/codetoanalyze/buck-out/gen/clang_compilation_database/__Hel lo#compilation-database.json
```
Also, some code in codetoanalyze/clang-compilation-database/ didn't compile, so
fix that.

Summary:
It is definitely useful to collect information about how long the analysis of every procedure takes. It allows to detect and focus on outliers when trying to improve performance. However, this kind of information could be collected using a standard logging mechanism and does not need to be stored within the analysis artifacts.
I intend to add some form of similar logging in the context of #16348004 once we can get every analysis procedure analyzed through the `Ondemand` module. In this case, it would be easy to have a single place to log how does the analysis of a procedure take.
