JDK-8031320 - Use Intel RTM instructions for locks
Description
Looking over nightly I saw some crushes in ciEnv::register_method(). They may be not related but I found a problem there with RTM changes.
nmethod::new_nmethod() may return NULL as result next instruction may cause crash:

#if INCLUDE_RTM_OPT
    nm->set_rtm_state(rtm_state);
#endif
