Summary:
This diff adds a layer of report deduplication logic in addition to
the existing scheme.
Suppose issue 1 with trace1a and trace1b, and issue 2 with trace2a and
trace2b. If trace1a ends at the same location as trace2a (resp.,
trace2b) and trace1b ends at the same location as trace2b (resp.,
trace2a), then consider issues 1 and 2 to be duplicates.
This chooses to report the issue with the smaller sum of trace
lengths, breaking ties using the issue hashes, and eventually the
entire issue. Therefore there is a potential for flakiness with
respect the the choice of which report to make within a
hash-equivalence class.

Summary: As Dulma pointed out, adding or removing paramters in a method in Objective C is changing the name of the method. Such changes should not make pre-exisiting issues reported as introduced. This diff is to prevent this by only keeping in the bug hash the part of the name that is before the first colon.

Summary: It is difficult to understand a lock consistency violation if error message includes an access path with a logical variable or a temporary variable as a base. As a temporary fix, we want to suppress all such warnings.

Summary:
Our model of unique_ptr and shared_ptr relied on the fact that we could C-style cast a pointer to the internal pointer type used in the smart pointer.
This is wrong when the smart pointer is used with a custom deleter that declares its own pointer type whose is not constructible from just a single pointer.

Summary: For the Buck integration for Java, caching when a summary is not found avoids going through the whole classpath every time a summary for the same method is not found.

Summary: This will avoid collisions when the inner classes are implementing the same methods. For example, the previous version of the bug hash could conflate the issues when several annonymous inner classes are implementing the same method, e.g. a annonymous subclass of `Runnable` implementing `run()`.

Summary:
Simpler bug hash that is more independent of the underlying analysis. This now computes the hash based on:
- the bug type.
- the base filename: i.e for my/source/File.java, just keep File.java. So the hash will not change when moving files around.
- the simple method name: i.e. without package information and list of parameters. So changing the list of parameters will not affect the bug hash.
- the error message were the line numbers have been removed. So moving code or reformatting will not affect the hash.
