Update loop-block testcases.
2010-01-06 Sebastian Pop <sebastian.pop@amd.com>
* graphite-blocking.c (scop_do_block): Print "SCoP will be loop
blocked" only when both the strip mine and the interchange have
been applied.
* testsuite/gcc.dg/graphite/block-2.c: Removed.
* testsuite/gcc.dg/graphite/block-3.c: Add scan pattern.
* testsuite/gcc.dg/graphite/block-4.c: Same.
* testsuite/gcc.dg/graphite/block-5.c: Same.
* testsuite/gcc.dg/graphite/block-6.c: Same.
