[scan-build] Whitelist all -fXXXX options.

[zaks.anna]

Please, provide more information on why this patch is needed and why the existing processing of the -f flags does not work as expected. Looks like the last modifications to the -f flags were made in r186138.

(Please, submit patches with more context: http://llvm.org/docs/Phabricator.html#requesting-a-review-via-the-web-interface)

Thank you!

Just realized that this is super old and has probably been fixed by r186138. Closing.
