[PATCH 0/2][graphite] Fix tonto and h264ref.

[Sebastian Pop]

The following patches fix two CPU2k6 benchmarks: tonto was miscompiled
with an infinite loop, and h264ref was ICEing.  Committed to the
graphite branch.

Sebastian Pop (2):
  Call scev_analyzable_p only on is_gimple_reg.
  Fix tonto: call propagate_expr_outside_region.
