      Description

      C2 crashes during build with the following stack:
      #0 0x00003fffb617df6c in JVMState::depth (this=0x0) at /usr/work/d056149/openjdk/jdk/src/hotspot/share/opto/callnode.hpp:260

      observe_safepoint() is called with jvms == NULL from fill_buffer with mach = CallLeafDirectNode. "_guaranteed_safepoint" needs to get set correctly for all MachCallNodes after JDK-8254231.

      In addition MachCallRuntimeNode::ret_addr_offset() need update for the new assertion in output.cpp.
