This implements a few closely related features: - Starts merging namespaces discovered inside imports. - Stores results of cross-package name lookup as an entry inside the scope. - Note this is particularly visible with `i32`. - Moves more of the imported instructions to the import scope. Note this is primarily for executing the namespace TODO in check.cpp, which is removed here. `testdata/namespace/merging_with_indirections.carbon` tests key behavior. --------- Co-authored-by: Richard Smith <richard@metafoo.co.uk>
