Add more read barriers for JNI roots.
To make it possible to concurrently scan the JNI global roots (that
is, the roots visited by JavaVMExt::VisitRoots()), add read barriers
to the indirect reference table and the reference table.
Also, add read barriers to the jmethodID/jfieldID decode routines
(ScopedObjectAccessAlreadyRunnable::DecodeField/DecodeMethod) so that
we can concurrently handle (encoded) fields and methods.

Add read barriers for the class and the intern tables.
Add read barriers for the strong roots in the intern table and the
(strong) roots in the class table to make possible concurrent scanning
of them.

Add a read barrier for weak roots in monitors.
A weak root requires a read barrier for the to-space invariant to hold
because the object pointed to by a weak root can't be marked/forwarded
like the one pointed to by a strong root (GC does not know if it's
alive or not at that point) and because, without a read barrier, a
mutator could access it and obtain a from-space reference, which would
violate the to-space invariant.
TODO: do similar for the other types of weak roots.

Replace the bool kDoReadBarrier template parameter with an enum.
Fix one kDoReadBarrier/kIsVolatile mixup in an Object::GetFieldObject
call.

Make the support code for read barriers a bit more general.
Add an option for Baker in addition to Brooks.
