      Description

      Command line switch descriptors in Hotspot are defined by "struct Flag" in
      globals.hpp. Each switch has a "type" field that says whether the switch
      is manageable, experimental, product, etc. Currently, "type" is a character
      string, and determining the switch type involves executing strcmp, which is
      a slow operation. What's more, a switch can be of only a single type.
      E.g., one can have a "manageable" switch and an "experimental" switch,
      but not a "manageable_experimental" switch.

      Hotspot should support multiple types per switch.
