This patch fixes Bug#14350
CreateWindowA("Edit"...) should create an Ansi window even after the builtin
Edit class has been subclassed by SetClassLongPtrW(hEdit,GCLP_WNDPROC,procW).
This bug applies to all builtin classes, but only Edit needs to be fixed
since in other builtin classes, user can not change the text in the control.
A->W->A conversion will get same string back. Edit is special since user
interact with it.
