[Bug tree-optimization/31966] Miscompiles valid code with -ftree-vectorize and -march=nocona

The behavior still exists in the 4.3 20070622 snapshot. It does not occur using
-march=core2 (the actual CPU in question). The bad value results when using
-ftree-vectorize and -march or -mtune =nocona. -O, -O2, or -O3 is also
required; a binary compiled with -Os produces the correct value.
