Fix compiler bug where duplicate type declarations caused crash.

And add missing test. The test runs and fails with the previous cfa compiler.

22// A SymbolTable that only tracks names relevant to Validate passes.
23// It tracks type names but not identifier names.
24// Some of the canonicalization that occurs before the resolver
25// affects how identifier name errors get reported to the user.
26// The Validate phase needs to chase type names,
27// but it is too early to try tracking identifier names.
28// Identifier skipping is acheived by omitting methods that should not be
29// called by the Pass template (lookupId and addId).
