Summary:
Let's introduce a set of new cost analysis issue types that are raised when the function is statically determined to run on the UI thread. For this, we rely on the existing `runs_on_ui_thread` check that is developed for RacerD. We also update the cost summary and `jsonbug.cost_item` to include whether a method is on the ui thread so that we don't repeatedly compute this at diff time for complexity increase issues.
Note that `*_UI_THREAD` cost issues are assumed to be more strict than `*_COLD_START` reports at the moment. Next, we can also consider adding a new issue type that combines both such as `*_UI_THREAD_AND_COLD_START` (i.e. for methods that are both on cold start and run on ui thread).

Summary: Use_after_free was used both for biabduction and pulse, and the biabduction version is blacklisted by default. As a result, the Pulse version was also disabled unintentionally. This changes the name of the old use_after_free so that now we can get use_after_free bugs whenever pulse is enabled.

Summary:
The models are only for biabduction so try to make that clearer in the
code and documentation.

Write a function to read in the summaries from the `.specs` folder
This is needed so the reverse analysis call graph can be constructed from the summaries

Summary:
- Add allocation costs to `costs-report.json` and enable diffing over allocation costs.
- Also, let's be more consistent and modular in naming our cost issues.
- introduce a generic issue type `X_TIME_COMPLEXITY_INCREASE` where `X` can be one of the cost kinds. If the function is on the cold start, issue can have the `COLD_START` suffix. Similarly for infinite/zero/expensive calls.
- Change `PERFORMANCE_VARIATION` -> `EXECUTION_TIME_COMPLEXITY_INCREASE`
- Add new issue type for `ALLOCATION_COMPLEXITY_INCREASE_COLD_START` which will be enabled by default
- Refactor cost issues to be more modular and succinct. This also makes addition of a new cost kind very easy by adding the kind into the `enabled_cost_kinds` list in `CostKind.ml`

Summary:
Adds option `--summary-stats` to `infer report`.
The formatting is not perfect yet but it gives what I want.

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:
First version of differential for costs, based on polynomial's degree's variation. The rule is very simple:
For a given polynomial that is available before and after a diff, `if degree_before > degree_after`, then the issue becomes `fixed`. Instead, `if degree_before < degree_after`, then the issue becomes `introduced`.
