RFR 8209844: MemberNameLeak.java fails when ResolvedMethod entry is not removed

[Patricio Chilano]

Hi all,

Could you review this change that addresses the intermittent failure of 
test MemberNameLeak.java after 8206423 ?
The test had intermittent failures due to the ServiceThread not being 
able to clean up the resolved method table before the process exited. 
Now a counter is used to guarantee entries in the table are removed 
before exiting. Also variables _oops_removed and _oops_counted were 
declared local in ResolvedMethodTable::unlink() since they are not used 
outside it.
