RFR (L) 8214502: Add space after/before {} in remaining vmTestbase tests

[JC Beyler]

Hi all,

Could I get a review for adding a space around the {} for the vmTestbase.
This webrev handles all remaining cases for vmTestbase :-)

Here is the webrev and bug:
Webrev: http://cr.openjdk.java.net/~jcbeyler/8214502/webrev.00/
Bug: https://bugs.openjdk.java.net/browse/JDK-8214502

Thanks for your help!
