Add inline test framework in fixall_test.go that runs @test assertions on both pre-fix and post-fix archives to verify fixes preserve semantics. The idea: @test attributes get copied by the fix the the new files as is. By testing both in and out, we ensure that the code generated by fix is correct. Add @test(eq) assertions to aliasv2 for field aliases, value aliases, and __self handling for demonstration. Fix compile errors in aliasv2.txtar: add missing variable definitions (x, name) for dynamic fields, add references to unused aliases (Z, OptField, ReqField, X, DynInterpAlias), fix Inner.Leaf.value to Inner.deep.value.
