When using a precompiled preamble, keep track of the top-level
declarations that we saw when creating the precompiled preamble, and
provide those declarations in addition to the declarations parsed in
the main source file when traversing top-level declarations. This
makes the use of precompiled preambles a pure optimization, rather
than changing the semantics of the parsed translation unit.
