Move inline caches GC handling in JitCodeCache.
Make the classes they hold weak references and visit
them during SweepJitRoots.
This fixes the newly introduced deadlock:
Thread1:
1) Lock JitCodeCache lock to create Profiling info for
ArtMethod m.
2) m is a copied method, we need to track the actual holder,
needing to decode a weak reference.
3) Weak references are not accessible due to GC.
GC Thread:
- Disallow weak reference access.
- Wait for checkpoint.
Thread2:
- Try to lock JitCodeCache lock
- Deadlock, as Thread1 owns the JitCodeCache lock.
