[9] RFR(S): 8059846: InstanceKlass should use MutexLockerEx to acquire OsrList_lock

[Coleen Phillimore]

This change looks good to me.  I suggest since nobody knows why this is 
here, that you remove it:

     // only one compilation can be active
     NEEDS_CLEANUP

It's old (from sccs):

renes 99/08/30    // only one compilation can be active
kbr 00/02/22      NEEDS_CLEANUP
