Log:
[NFCI] Explicitly provide user-defined constructor for SectionRef

I am changing this to work around an issue that is being hit when
building with clang 3.8. Specifically, clang 3.8 requires that we have a user
defined default constructor for SectionRef for the default initialization of a
const SectionRef.
