Description
postalloc_expand_java_dynamic_call_sched should copy also MachSafePointNode::_has_ea_local_in_scope

If the information is not propagated then it can happen that C2 optimizations based on escape analysis are not reverted when an object reference escapes because an JVMTI agent reads it.
Comments
Fix request (23u) I would like to do the backport to fix the issue described above. The included regression test demonstrates a variant of the issue. It fails without the fix. The backport applies cleanly. The fix passed our CI testing: JTReg tests: tier1-4 of hotspot and jdk. All of Langtools and jaxp. JCK, Renaissance Suite, and SAP specific tests. Testing was done with fastdebug builds on the main platforms and also on Linux/PPC64le. Risk is low. The change affects only PPC64 and the field that is changed is only read in the JVMTI implementation. Also the change includes a regression test. Thanks, Richard.
