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

[Gerard Ziemski]

Hi all,

Here is webrev 2 with the following additions:

#1 Factor FlagSetting class out of "runtime/flags/jvmFlag.hpp" and into its own "runtime/flags/flagSetting.hpp", so that FlagSetting class can extend from “public StackObj” (thanks Coleen)

#2 change the hierarchy from “runtime/jvmFlag/“ to "runtime/flags/“ (thanks David)

#3 Fix the header files, so that both closed and open repository build with and without precompiled headers

#4 Add “runtime/flags/*.hpp” headers to “precompiled.hpp”

The number of touched files got even longer - sorry about that and big thank you for taking your time to review!

Running final Mach5 hs_tier1-5 tests… (it passed earlier iterations). Passes local builds (on Mac OS X) with and without precompiled headers for both closed and open repos and both debug and product versions (should I try any other build varations?)
