Reducing the optimization level to -O1 -fgraphite-identity still causes a
segfault, but in a different place:

Seems to work on 32-bit x86

Ignore the previous comment -- it working on x86 (32bit) was caused by not
having -fgraphite-identity in the CFLAGS there. It crashes everywhere.

Same problem on 64 bits, but it is one of the -O1 optimisations that does it.

Depends on how difficult it would be to backport the fix.
I haven't git-bisect'ed it to know which of the patches fixed it.

trunk@169530 works.
I tested the original and reduced testcases with -fgraphite-identity and either
-O2 or -O1.
