When updating reference is piggy-backed on marking phase, we need to
resolve oops that we get in SATB buffers before checking if they are
marked, because from-space oops never get marked. This generates
unnecessary traffic in SATB.
Fix is to add template to requires_marking() that optionally resolves
the object, and use that when we may see forwarded objects.
Testing: hotspot_gc_shenandoah looks good
