RFR: 8305252: make_method_handle_intrinsic may call java code under a lock

[Coleen Phillimore]

This change adds an entry to the method intrinsic table without the Method and creates one later.  Racing threads wait() to get the method.  This is somewhat more complicated but avoids having to flush the Method and compiled nmethod for the thread that loses the race.
Tested with tier1-4.
