layout: Unify layout logic for replaced and non-replaced floats&atomics (#37897)

Laying out a float or atomic inline will now use the same logic
regardless of whether it's replaced or not.
This reduces the amount of code, and should have no observable effect.

Testing: Unneeded (no behavior change)
