RFR(S): 8064696: compiler/startup/SmallCodeCacheStartup.java doesn't check exit code

[Tatiana Pivovarova]

Hi,

please review this patch

Bug: https://bugs.openjdk.java.net/browse/JDK-8064696
Webrev: http://cr.openjdk.java.net/~iignatyev/tpivovarova/8064696/webrev.00

compiler/startup/SmallCodeCacheStartup.java starts a new process, but 
doesn't check its exit code.

Fix:
- added check of exit code via OutputAnalizer
- removed recursion (call vm with option "-version" instead 
"SmallCodeCacheStartup")

testing: Manually. As expected: fails in 8-b112 and passed in 8-b113 
(and latest 9-b40).

Thanks,
Tatiana
