RFR: 8148741: compiler/jvmci/code/SimpleDebugInfoTest.java fails in 'frame::sender_for_compiled_frame'

[Roland Schatz]

Hi,

Please review this bugfix:

webrev:
http://cr.openjdk.java.net/~rschatz/JDK-8148741/webrev.00/
issue:
https://bugs.openjdk.java.net/browse/JDK-8148741

This is on top of another open RFR [1]. These are two separate but 
related bugs. Both fixes are needed for the test to pass.

Thanks,
Roland
