Gabor Horvath 857ccd2919 [analyzer][GSoC] Re-implemente current virtual calls checker in a path-sensitive way 
Patch by: Xin Wang

Devin Coughlin 3e5f0474ca [analyzer] Improve VirtualCallChecker diagnostics and move into optin package. 
The VirtualCallChecker is in alpha because its interprocedural diagnostics
represent the call path textually in the diagnostic message rather than with a
path sensitive diagnostic.

This patch turns off the AST-based interprocedural analysis in the checker so
that no call path is needed and improves with diagnostic text. With these
changes, the checker is ready to be moved into the optin package.

Ultimately the right fix is to rewrite this checker to be path sensitive -- but
there is still value in enabling the checker for intraprocedural analysis only
The interprocedural mode can be re-enabled with an -analyzer-config flag.

Jordan Rose d8665b3d1a [analyzer] Don't run non-path-sensitive checks on system headers... 
...but do run them on user headers.

Previously, we were inconsistent here: non-path-sensitive checks on code
/bodies/ were only run in the main source file, but checks on
/declarations/ were run in /all/ headers. Neither of those is the
behavior we want.

Thanks to Sujit for pointing this out!
