[jdk11u-dev] RFR: 8254244: Some code emitted by TemplateTable::branch is unused when running TieredCompilation

[Dmitry Chuyko]

This is a small interpreter optimization for few CPU architectures (shared, ppc and sparc are not touched).

Original patch applies successfully. There is fuzz 1 for one hunk (#1) in templateTable_arm.cpp with changes applied in the right place (dispatch_only has 1 arg as thread-local handshakes for arm32 are not backported).

Testing: tier1, tier2 (amd64, aarch64).
