RFR - JDK-8179625 [BACKOUT] of 8179305 Avoid repeated calls to JavaThread::last_frame in InterpreterRuntime

[Ioi Lam]

Hi,

It turns out JDK- 8179305 causes intermittent failures in JPRT, so it 
needs to be backed out quickly:

https://bugs.openjdk.java.net/browse/JDK-8179625
http://cr.openjdk.java.net/~iklam/jdk10/8179625-backout-8179305-last-frame.v01/

Thanks
