So far CSA was relying on the LLVM Statistic package that allowed us to gather some data about analysis of an entire translation unit. However, the translation unit consists of a collection of loosely related entry points. Aggregating data across multiple such entry points is often counter productive. This change introduces a new lightweight always-on facility to collect Boolean or numerical statistics for each entry point and dump them in a CSV format. Such format makes it easy to aggregate data across multiple translation units and analyze it with common data-processing tools. We break down the existing statistics that were collected on the per-TU basis into values per entry point. Additionally, we enable the statistics unconditionally (STATISTIC -> ALWAYS_ENABLED_STATISTIC) to facilitate their use (you can gather the data with a simple run-time flag rather than having to recompile the analyzer). These statistics are very light and add virtually no overhead. Co-authored-by: Balazs Benics <benicsbalazs@gmail.com> CPP-6160
