RFR(S): JDK-8032250 : Add trace event for VM flag changes

[Staffan Larsen]

Erik Helin suggested using template functions instead of macros which makes the code a little more type safe.

Also added a missing #include in globals.cpp.

Here is a new version of the webrev: http://cr.openjdk.java.net/~sla/8032250/webrev.01/

Thanks,
