Original commit message:

[coverage] Correctly free DebugInfo in the absence of breakpoints

It's quite possible for DebugInfos to exist without the presence of a
bytecode array, since DebugInfos are created for all functions for which
we have a CoverageInfo. Free such objects properly.

Also move the corresponding deletion of CoverageInfos on unload up
before the early exit.
