RFR: JDK-8151656: Minor tweaks to old Hotspot build to ease comparison with new

[Erik Joelsson]

In preparation for the new Hotspot build, there are a few changes to the 
old build that needs to happen first. These changes should be harmless, 
but do impact the generated binaries some. These changes are:

* Standardizing sort order for objects on link command line on Windows 
to a locale independent order.
* Working around compare differences caused by the __FILE__ macro in 
certain generated files by overriding the value of __FILE__ in those files.

By making these changes first and separate from introducing the new 
build we reduce the potential impact of when we do introduce the new build.
