miri: add flag to suppress float non-determinism We have flags controlling most non-determinism, so this seems generally useful for debugging. It is also needed to work around rust-lang/portable-simd#463 in miri-test-libstd. I made this a rustc PR so that it propagates faster to unbreak miri-test-libstd. r? `@oli-obk`
