[PATCH] Add printing functions to tree-affine.c

[PATCH] Add printing functions to tree-affine.c

Hi,
  While working on iv-opts and tree-affine, I found it was hard to
quickly print out aff_tree and get useful information out.  This patch
adds two functions to tree-affine.c to print out an aff_tree*.

OK? Bootstrapped and tested on i386-apple-darwin8.10 with no regressions.

Thanks,
Andrew Pinski

ChangeLog:

* tree-affine.h (print_aff): New prototype.
(debug_aff): Likewise.
* tree-affine.c (print_aff): New function.
(debug_aff): Likewise.

No need to specify argument names here.

Needs comment.

Likewise.

s/elments/elements/

OK with those changes.
