the fix appears to be to align the
out struct on an 8 boundary, but that
is a bit involved.

change type (to satisfy OAS) after nodarg:
nodarg uses offset from type too,

  - moved Object, Type, Scope  out of AST into symboltable
  - moved universe into symboltable
  - removed dead code
- fixed dependency computation (pretty -d filename.go)
- lots of cleanups

is not right if the .6 is only for data and
