[PATCH] D47460: Treat files as volatile by default

Memory mapping locks the file on Windows. That means that in the addressed case it locks main file which we are editing. After that happens many tools struggle to do something with this file, for example git.
It's the quickest solution, probably not the best. Better one would introduce isVolatile parameter in FileSystem::getBufferForFile which should be set to true somewhere (I didn't have to to search for the specific location yet)
