This port is not used and is not being worked on, so remove it to reduce the amount of the code which needs to be updated for every global change. Also remove tests for VisualAge compiler which isn't used since ages. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@76533 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
