Hi all,

could you please review this small (and hopefully trivial) patch which converts internal GCTimer_test to gtest?

webrev: http://cr.openjdk.java.net/~iignatyev//8157728/webrev.00/index.html
JBS: https://bugs.openjdk.java.net/browse/JDK-8157728
testing:
 - converted tests on linux-x64, windows-x64, macosx-x64, solaris-sparcv9 in product and fastdebug variants 
 - build w/ precompiled-headers enabled and disabled

PS the patch has been originally created by Kirill Zh, but hasn't been sent out for official review

Thanks,
-- Igor
