PRE now confuses graphite. No idea why and no chance I'll dive into graphite
to figure it out. Maybe Sebastian can have a look, otherwise I'll XFAIL the
tests after a while (or add -fno-tree-pre to them).
My testing machine had too old ppl so I missed the fails.

The loop nest is not perfect, in interchange-15.c:
for (i = 0; i < N; i++)
for (j = 0; j < N; j++)
x[i] += a[j][i];
used to be perfect nest, now we have x[i] read and written in
the outer loop, enough to confuse loop interchange.
Please XFail the testcases, or change them to only have a
scalar reduction:
for (i = 0; i < N; i++)
for (j = 0; j < N; j++)
x += a[j][i];

All 3 tests now XPASS everywhere. It seems the XFAILs can be removed?
