RFR: 8366461: Remove obsolete method handle invoke logic [v4]

[Dean Long]

> At one time, JSR292 support needed special logic to save and restore SP across method handle instrinsic calls, but that is no longer the case. 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)).
