RFR: 8248362: JVMTI frame operations should use Thread-Local Handshake

[Yasumasa Suenaga]

Hi all,

Please review this change:

   JBS: https://bugs.openjdk.java.net/browse/JDK-8248362
   webrev: http://cr.openjdk.java.net/~ysuenaga/JDK-8248362/webrev.00/

Migrate JVMTI frame operations to Thread-Local Handshakes from VM Operations.

     - VM_GetFrameCount
     - VM_GetFrameLocation

They affects both GetFrameCount() and GetFrameLocation() JVMTI functions.

This change has passed all tests on submit repo (mach5-one-ysuenaga-JDK-8248362-20200722-1249-12859056), and vmTestbase/nsk/{jdi,jdw,jvmti}, serviceability/{jdwp,jvmti} .


Thanks,

Yasumasa
