[PATCH] D12095: propagate fast-math-flags on DAG nodes

It's good on our test suite. There's regressions initially, but literally all of them go away when I apply my patch for passing through DAG flags in our target-specific DAG combines. I think it's actually NFC across ~10,000 shaders when that second patch is applied.
