George Karpenkov ef9eb3e6cd [analyzer] [tests] Add an option for showing statistics after running tests. 
Do not show statistics by default.

George Karpenkov de212366a3 [analyzer] [tests] [NFC] Remove dead code from CmpRuns 
Indeed, "CHANGE" is not a thing yet, and we should probably not carry
around dead code which does not do anything apart from confusing the
reader.

George Karpenkov d578df7f78 [Analyzer] Refactor analyzer testing scripts. 
- Exporting needed function for future reuse.
 - Idiomatic python: using with `file as f` instead of `try/finally`.
 - Fixing some indentation issues.
 - No need to reinvent python `multiprocessing.getCPUCount()`
 - Removing a function parameter which is always the same under all invocations.
 - Adding some docstrings.

Gabor Horvath 61a690a04f [analyzer] Bug identification 
This patch adds hashes to the plist and html output to be able to identfy bugs
for suppressing false positives or diff results against a baseline. This hash
aims to be resilient for code evolution and is usable to identify bugs in two
different snapshots of the same software. One missing piece however is a 
permanent unique identifier of the checker that produces the warning. Once that
issue is resolved, the hashes generated are going to change. Until that point
this feature is marked experimental, but it is suitable for early adoption.

Jordan Rose e30024c96f [analyzer] CmpRuns.py: Accept single files as input.

Anna Zaks 2a84b8bd10 [analyzer] CmpRuns should include file name in the issue identifier. 
This prevents us from treating the issues from different files with the
same function names and same offsets as the same.

The issue identifier now includes the file name. Also added a way to
strip off the root directories form the source file names.

CmpRuns can be used for static analyzer bug report comparison. However,

friendly/documented API for CmpRuns script.
