Most of the instructions, which can perform the operation to load immediate value on condition, are not supported on s390x (openjdk). So those could be added and hotspot code could be refactored with usage of these instruction for both readability & performance of code.

To some places it can save us branch cost, one example is here in this PR: https://github.com/openjdk/jdk/pull/19544.

It makes sense to backport it to past version, if there is any benefit.
