a81e7a52fc 8033443: Test8000311 fails after latest changes to parallelize string and symbol table unlink

90c553c06f 6991197: G1: specialize deal_with_reference() for narrowOop* 
Clean up and slightly optimize reference handling from the GC reference task queue. Since we never push partial array chunks as narrowOop* we can manually specialize the code so that some code can be optimized away.

The field G1AllocRegion::_alloc_region needs to be declared volatile as it is used with that intention. Otherwise the compiler may generate the code that reloads the value which might have changed in the meantime, leading to spurious crashes.
