Emit global-scope parameters from imported files.

This fixes up a bug in the earlier change that provided reflection for imported parameters; I'd failed to confirm that the code generation logic can handle imported parameters correctly.

The main fix was to have an `import` declaration automatically use the global-scope layout already determined, sine imported parameters will in general appear there.
