      Description

      There has been a noticeable dip in bloat performance (was hovering around 96-98%, now around 90-92%). See attached graph, available at [1] if you're lucky.

      On close inspection, the dip occurred between performance runs 6694 & 6699, which points to the commits 15225-15227.

      15225: Switch use of StringBuffer to StringBuilder
      15226: RVM-725 Closed WIP: make naming of opt compiler options more regular. Introduce options for local expression folding and tableswitch conversion.
      15227: RVM-725 Closed WIP: introduce new options to control bonuses given to reduce the method size when particular arguments are passed to a method being considered for inlining.
