* Count new clang-tidy warnings:
google-runtime-references
google-runtime-operator
* Count new clang warnings:
-Wconst-conversion similar to -Wliteral-conversion
-Wundefined-var-template
* Modified static analyzer warning message about
"Null passed to a callee that requires a non-null ..."
* Disable google-runtime-references by default and
disable misc-macro-parentheses in vendor projects;
too many old C/C++ code have this warning.
