From: hiraditya <hiraditya@msn.com>

No functional changes intended. Passes make check and bootstrap.
gcc/ChangeLog:

2015-09-29  Aditya Kumar  <hiraditya@msn.com>

        * graphite-dependences.c (scop_get_dependences): Moved in down
	in order to be visible to its caller.
        * graphite-poly.h: Removed compute_deps, and extend_schedule.
