This is fix for P1 in JDK 9.

After JDK 9 version string changed from "9-ea+174" to "9+176" Graal stop 
working because it does not recognize this version string. It looked for 
"9-ea". As result AOT does not work and all AOT [1] and JVMCI tests fail.

The same problem also exists in JDK 10 but we did not hit it yet because 
we did not test AOT in *promoted* builds yet. Our current jdk 10 builds 
(from JPRT) have "internal" in version string and Graal's version check 
accepts it.

The fix changed jdk 9 version check to "9+" and removed failure exit for 
other versions including 10:

+      } else {
+          // Graal will be compatible with all JDK versions as of 9 GA
+          // until a JVMCI API change is made in a 9u or later release.


And the code is updated (added try{}) to match one in JDK 10 [2].

Thanks,
Vladimir
