X87: [interpreter] First implementation of stack unwinding.

  port 0b3066b8f5d914bb1a8c5dd0404a866d389d7798 (r33414)

  original commit message:
  This implements a first prototype of stack unwinding for interpreted
  frames. The unwinding machinery performs a range-based lookup in the
  given handler table and potentially continues dispatching at the handler
  offset. Note that this does not yet correctly restore the context to the
  correct value when the handler is being entered.
