Subject: [PATCH] fix clang warnings in folly::Gen

Summary: Two clang warnings. It wants user defined consturctor for static initialization, and it wants fwd-declare to agree with full decleration in regards to struct v class.

Test Plan:
`fbconfig --clang --platform=gcc-4.7.1-glibc-2.14.1 folly/test/`

And make sure it doesn't break normal build.
