This is a fix for this particular bug: I am considering this bug closed, and I
will close it when the patch will be in trunk.

Disabling one of the useless gcc_asserts that verifies the consistency of the
original representation before any transform, I am down to 0 seconds for the
data dependence test, and the following compile times for

Does r151102 address the exponential code generation in graphite generally or
just that for this particular test case?

This still fails on rev150694. The problem is in the data dependence analyzer:
Graphite loop transforms: 0.34 ( 0%) usr 0.00 ( 0%) sys 0.29 (0%) wall
2105 kB ( 7%) ggc
Graphite data dep analysis: 107.68

Checked against the 4.4 branch, with the following timings:
4.4 w/o1.79
w 1.80
4.5 w/o4.23
w144.30

What|Removed
What changed from 4.4 to 4.5 is that we now get to compile larger
SCoPs with Graphite. In 4.5, Graphite can deal with reductions and
other unhandled constructs like the NE_EXPR that Fortran is frequently
using for representing the exit condition of DO loops.
