Tests that rely on the old perf benchmark harness need porting to use JMH

The relevant tests are:

com.hp.mwtests.ts.jts.orbspecific.local.performance.Performance1
com.hp.mwtests.ts.jts.orbspecific.local.performance.Performance2
com.hp.mwtests.ts.jts.orbspecific.local.performance.Performance3

if there are no others then once ported the old performance benchmark harness can be removed.
