        Description

        G1ParGCAllocator::alloc_buffer_waste tracks the waste at the end of a PLAB caused by throwing away that TLAB.

        Remove it as this information is duplicated by PLABStats::waste(), with the additional problem that alloc_buffer waste does not include all waste. It misses the waste at the end of a PLAB that is reserved to put a filler object into to guarantee parsability of the heap.

        The value can be replaced by the sum of survivor/old PLABStats::waste().
