[PATCH] Remove ordinals from Input Graph elements.

[Shankar Kalpathi Easwaran]

  a) This is the only thing that we have to know the position of files that appeared in the command line and if there is a need to reorder to command line similar to lorder within lld.

  http://www.unix.com/man-page/linux/1/LORDER/ may give you more information.

  b) Users can set ordinals and change the command line order if they dont want the input element to be placed at that position. I believe MachO had a requirement on the InputGraph to move input elements to the end if they are libraries.

  If Nick/Michael feel its not needed to do this, then I would be ok to remove it.
