Review Request (S) 8015436: compiler/ciReplay/TestSA.sh fails with assert() index is out of bounds

Please, review the fix and unit test for:
   bug: http://bugs.sun.com/view_bug.do?bug_id=8015436
   jbs:  https://jbs.oracle.com/bugs/browse/JDK-8015436

Open webrev:
http://cr.openjdk.java.net/~sspitsyn/webrevs/2013/hotspot/8015436-JVMTI-JSR292.1

Summary:
   The InstanceKlass _initial_method_idnum value must be adjusted as 
necessary if the overpass methods are added.
   I guess, it is Ok to integrate a unit test covering the fix under the 
same bug id.

Testing:
   Newly added hotspot unit test: compiler/8015436/Test8015436.java
   The originally failed test:    compiler/ciReplay/TestSA.sh
   The vm/mlvm tests

Thanks,
Serguei
