X-VarHandleTestXXX.java.template changes look wrong and maybe merge issue.  These files were updated recently.

For VarHandles tests, you only need to modify X-VarHandleTestXXX.java.template files to add `-XX:+EnablePrimitiveClasses` flag and then run `test/jdk/java/lang/invoke/VarHandles/generate-vh-tests.sh` that will regenerate the `test/jdk/java/lang/invoke/VarHandles/VarHandle*` tests.
