This PR makes handling of floating reads uniform. They are never introduced unless FloatingReadsPhase has been run. This only meaningful changes are in DefaultHotSpotLoweringProvider, where a few cases were still introducing FloatingReadNodes, and the use of FloatingReadsPhase during snippet preparation. Everything else is about propagating the GraphState into snippet preparation.

Benchmark results seem fine.
