Bug is fixed in graphite branch.  Waiting review for trunk.

Created an attachment (id=16435)
 --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=16435&action=view)
This patch fixes the reduced test case block-3.c

Until graphite can handle scalars and also update dominance properly (planned
for gcc 4.5), this patch will work by limiting the scop that contains bb 3,
which in turn contains the VDEFs for SMT.48_20, SMT.49_21, such that no code is
generated for it.

This patch depends on the patch submitted for 37485.
