8270041: Consolidate oopDesc::cas_forward_to() and oopDesc::forward_to_atomic()

[rkennke]

The two methods do exactly the same, except one returns a bool, the other a value. The only use of cas_forward_to() can be consolidated to use forward_to_atomic() instead.

Testing:

• hotspot_gc
• tier1
• tier2
