  [llvm-jitlink] Wait for reachable files to link before running checks.

ORC dependence tracking is fine-grained (i.e. per-symbol), however when running
-check mode we want to wait for all links triggered by the entry point lookup
to complete, regardless of whether the code / data in them is actually
reachable from the entry point. This simplifies test-cases, since authors don't
need to reason about per-symbol dependencies to know that additional files will
be linked (if referenced transitively in any way from the test-case).

The new Session::waitForFilesLinkedFromEntryPointFile utility does _not_ wait
for lazily linked (-lazy) files.

This will be used to fix buildbot errors caused by edca1d9bad2.
