RFR (XS): 8203318: compiler/stable/TestStableShort.java is broken

[Ekaterina Pavlova]

Hi all,

Following tests were accidentally changed some time ago and as result are currently ran 4 times in the same configuration
instead of running in 4 different configurations (C2 + FoldStableValues, C2 - FoldStableValues, C1 + FoldStableValues, C1 - FoldStableValues):

  compiler/stable/TestStableByte.java
  compiler/stable/TestStableChar.java
  compiler/stable/TestStableDouble.java
  compiler/stable/TestStableFloat.java
  compiler/stable/TestStableInt.java
  compiler/stable/TestStableLong.java
  compiler/stable/TestStableObject.java
  compiler/stable/TestStableShort.java

Please review the fix which reverts proper configurations to run tests in.

     jbs: https://bugs.openjdk.java.net/browse/JDK-8203318
  webrev: http://cr.openjdk.java.net/~epavlova//8203318/webrev.00/

testing: tested by running all compiler/stable tests on 8 platforms.


thanks,
