e5e40e58 - [ClangImporter] Filter import-as-member decls by preferred submodule. (#10626)

[ClangImporter] Filter import-as-member decls by preferred submodule. (#10626) That is, if a member is redeclarable, use the module of the definition if possible, and the canonical declaration otherwise. This is consistent with what we do when we actually import the declaration. Without this, we can end up dropping declarations. rdar://problem/32816381 (#10612)
