X87: Simplify pending message script handling.

X87: Simplify pending message script handling.

port f71e26268338d2840133264329bf35a63011bb5a (r27127)

original commit message:

  Simplify pending message script handling.

  This removes the separate tracking of the pending message script,
  because that script is already stored in the message object and
  duplicating it in the ThreadLocalTop makes it more brittle.
