[Bug tree-optimization/37449] [4.4 Regression] calculix gets wrong answer for -O1 -ffast-math

There's a Heisenbug involved here.  A reghunt for failures with "-O1 -ftree-fre
-funsafe-math-optimizations" came up with a nonsensical result, and I can
sometimes get it to fail with only "-O1 -funsafe-math-optimizations".
