RFR: 8357962: JFR Cooperative Sampling reveals inconsistent interpreter frames as part of JVMTI PopFrame

[Markus Grönlund]

Greetings,

Please see the JIRA issue for a detailed description. 

Fix only applies to platforms that issue a save_bcp() as part of InterpreterMacroAssembler::unlock_object().

Testing: jdk_jfr, JVMTI PopFrame tests

Thanks
Markus
