Tune rosalloc buffer sizes.
We now use one-page buffers for size brackets 4-7, instead of two-page
buffers, and the first 8 size brackets for thread-local allocations,
instead of 11.
No slowdown observed with MemAllocTest, EvaluateAndApplyChanges, and
BinaryTrees.
(cherrypick commit c4cd95fa37b7138a0fa26d07c235aa409542aecd)
