Nit: I don't think we generally do this sort of scoped `using`. And really, why
not just put the infobar itself into the `password_manager` namespace?

I'm OK with it if it makes the code below noticeably more readable.  Otherwise
it could go away.  Don't care much.

(I'm always happier with function-scoped using than file-scoped using.)

Putting the infobar in the namespace might make sense.  Or getting rid of the
password_manager namespace entirely... our namespace policy across Chromium
seems rather inconsistent, I usually end up just avoiding namespaces.

+    return;
+  }
+  DCHECK(credential_type == CredentialType::CREDENTIAL_TYPE_LOCAL ||
+         credential_type == CredentialType::CREDENTIAL_TYPE_FEDERATED);
+  auto& credentials_forms =
+      (credential_type == CredentialType::CREDENTIAL_TYPE_LOCAL)

Nit: You don't need the () here.

No, but I think it makes things a little more readable.  Up to you guys though.
