h/t to @samsinsane for original PR on which this is based (#741)
I must not have been on the latest revision when I merged the Xcode module into core. This catches things back up to the state of the submodule repository.
As discussed numerous times, get rid of the submodule approach for core modules and just included the sources directly in the main repository.
I have no idea how this will play with existing working copies. It might be necessary to [manually clear out the existing submodules](http://stackoverflow.com/questions/1260748) first.
A number of tests were relying on the fact that x32/x64 were being converted implicitly to x86/x86_64. If/when we retire those symbols, all of those tests would break. Renamed them now to avoid having to sort it out later. Also fixed up comments to keep everything consistent.
