      TLABWasteIncrement=max_intx is okay for G1 on SPARC but other collectors fires an assert.
      ThreadLocalAllocBuffer::refill_waste_limit_increment() is directly used at 'add' instruction but only 13bits are used on that.

      In addition, as current TestOptionsWithRanges.java tests only for default garbage collector if there is no dependency on the flag, we couldn't find this issue before.
      With JDK-8144578 fixed, we don't need a new test for all collectors.
