This is to avoid a lock inversion problem. In many situation, the
{NativeModule} lock is held while getting the {DebugInfo} lock.
Hence we should never do is the other way around, otherwise we risk a
deadlock.
When setting a breakpoint, we hold the {DebugInfo} lock when triggering
recompilation, but recompilation accesses the {NativeModule} for
creating the {CompilationEnv}, and therefore takes the {NativeModule}
lock.
This CL fixes this lock inversion by giving up the {DebugInfo} lock
before recompiling functions.
