With these changes it is possible to run Graal’s bytecode unit tests.

The patch includes a change in src/share/vm/jvmci/jvmciCodeInstaller.cpp to use PrintNMethods and CompileCommand directives to print disassembly when code installation is not going through the broker.

Also, it includes a fix for a mis-merge in src/share/vm/runtime/frame.cpp which broke printing of method names for JVMCI compiled methods:

# J 20 JVMCI  (null)null (196 bytes) @ 0x00007fb38a369f2f [0x00007fb38a369e80+0x00000000000000af]
