Given Decl::isUsed() a flag indicating when to consider the "used"
attribute as part of the calculation. Sema::MarkDeclReferenced(), and
a few other places, want only to consider the "used" bit to determine,
e.g, whether to perform template instantiation. Fixes a linkage issue
with Boost.Serialization.
