Now I implemented the optimization in macroAssembler, also for the

Unfortunately it's only used in the methodHandles code.
Testing took a bit because the results were spoiled by unrelated problems.

Don't you have to make (or want to make) changes to
MacroAssembler::decode_heap_oop_not_null in the macro assembler files?
