The only platform that still does the save/restore is arm32, which is no longer necessary. The save/restore can be removed along with related APIs and logic. Note that the arm32 port is largely based on the x86 port, which stopped doing the save/restore in jdk9 ([JDK-8068945](https://bugs.openjdk.org/browse/JDK-8068945)).
