      Description

      Proposal for test improvement - test should use significant part of heap for humongous allocation.

      From mail threads:

      http://mail.openjdk.java.net/pipermail/hotspot-gc-dev/2016-December/019371.html

      Not sure if that significantly changes the tests. Running with 32M
      regions with 512M of heap does not seem to make a lot of sense, but
      previously it has only been 1g either.

      One option could be to make two tests out of the one, one for 32 bits,
      one for 64 bits. But the previous 1g heap has already been a random
      guess too, so I do not know.

      http://mail.openjdk.java.net/pipermail/hotspot-gc-dev/2016-December/019368.html:

      Bit of nitpicking - it could look nicer if you sort @runs basing on G1HeapRegionSize (from 1M to 32M or vice versa) but it's up to you.
