Two source-compatibility fills, surfaced compiling larger Go programs under TinyGo: - runtime.Func.Entry: stubbed like the rest of runtime.Func; testify's mock package calls FileLine(f.Entry()). - runtime/pprof goroutine-label API (Labels, Label, ForLabels, WithLabels, SetGoroutineLabels, Do): inert stubs alongside the existing pprof stubs; google.golang.org/grpc references them. Do still calls f, labels are simply not attached.
