Log:
[clang-scan-deps] Support for clang --analyze in clang-scan-deps

The goal is to have 100% fidelity in clang-scan-deps behavior when
--analyze is present in compilation command.

At the same time I don't want to break clang-tidy which expects
__static_analyzer__ macro defined as built-in.

I introduce new cc1 options (-setup-static-analyzer) that controls
the macro definition and is conditionally set in driver.
