Remove virtual methods from CodeBlob and nmethod to simplify saving/restoring in Leyden AOT cache. It avoids the need to patch hidden VPTR pointer to class's virtual table.
Added C++ static asserts to make sure no virtual methods are added in a future. Fixed/cleaned SA code which process CodeBlob and its subclasses. Use `CodeBlob::_kind` field value to determine the type of blob. Tested tier1-5, hs-tier6-rt (for JFR testing), stress, xcomp ------------- Commit messages: - 8349088: De-virtualize Codeblob and nmethod Changes: https://git.openjdk.org/jdk/pull/23533/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=23533&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8349088 Stats: 518 lines in 23 files changed: 235 ins; 215 del; 68 mod Patch: https://git.openjdk.org/jdk/pull/23533.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/23533/head:pull/23533 PR: https://git.openjdk.org/jdk/pull/23533
