Rollup merge of #89184 - joshtriplett:master, r=estebank

Temporarily rename int_roundings functions to avoid conflicts These functions are unstable, but because they're inherent they still introduce conflicts with stable trait functions in crates. Temporarily rename them to fix these conflicts, until we can resolve those conflicts in a better way.
