X87: [builtins] Add receiver to builtin exit frames.

  port f59a2335 (r37500)

  original commit message:
  Stack trace generation requires access to the receiver; and while the
  receiver is already on the stack, we cannot determine its position
  during stack trace generation (it's stored in argv[0], and argc is only
  stored in a callee-saved register).

  This patch grants access to the receiver by pushing argc onto builtin
  exit frames as an extra argument. Compared to simply pushing the
  receiver, this requires an additional dereference during stack trace
  generation, but one fewer during builtin calls.
