Matt Pharr b3c5043dcc Don't enable llvm's UnsafeFPMath option when --opt=fast-math is supplied. ...

This was causing functions like round() to fail on SSE2, since it has code
that does:

    x += 0x1.0p23f;
    x -= 0x1.0p23f;

which was in turn being undesirably optimized away.

Fixes issue #211.
