Description
There is a consensus in https://github.com/openjdk/jdk/pull/22567 that we should first remove the easy parts of 32-bit x86 port from mainline, and then do deeper cleanups in Hotspot code that would be enabled by the 32-bit x86 port removal.

This umbrella task tracks this deep cleanup work.
