Patch to allow machine depenendend reorgs to dump extra info

[Nick Clifton <nickc at cygnus dot com>]

Hi Guys,

  I would like to submit the small patch below for approval.  It
  simply changes the RTL dumping code for the machine dependent
  reorganisation pass (if there is one), so that the pass itself can
  put extra information into the dump file.

Cheers
	Nick

	reorganisation pass to place information into the RTL dump
	file if it so wishes.
