RFR (XL) 8081519 Split globals.hpp to factor out the Flag class

How does this file get the include for JVMFlag?   I don't see 
jvmFlag.hpp included anywhere but one cpp file.

http://cr.openjdk.java.net/~gziemski/8081519_rev2/src/hotspot/share/runtime/jvmFlag/jvmFlagConstraintsCompiler.hpp.udiff.html

Shouldn't this #include jvmFlag.hpp too?

I can't find anything that includes jvmFlag.hpp except jvmFlag.cpp but 
there are many files that have JVMFlag::Error in them.

This is a nice refactoring!

thanks,
Coleen
