JVMTI PopFrame support

Implement support for the JVMTI can_pop_frames capability. This works
by marking shadow-frames with a bit that forces it to be popped or an
instruction to be retried. When a PopFrame is requested the plugin
will deoptimize the targeted thread and force the interpreter to deal
with the frame pop. If the can_pop_frames capability is enabled the
runtime will be forced to handle all exceptions through the
interpreter. This is required to support PopFrame during some
exception events.
