prog: remove Dir from Type
Having Dir is Type is handy, but forces us to duplicate lots of types. E.g. if a struct is referenced as both in and out, then we need to have 2 copies and 2 copies of structs/types it includes. If also prevents us from having the struct type as struct identity (because we can have up to 3 of them). Revert to the old way we used to do it: propagate Dir as we walk syscall arguments. This moves lots of dir passing from pkg/compiler to prog package. Now Arg contains the dir, so once we build the tree, we can use dirs as before. Reduces size of sys/linux/gen/amd64.go from 6058336 to 5661150 (-6.6%). Update #1580
