Russ Cox	4224d81fae	cmd/internal/gc: inline x := y.(*T) and x, ok := y.(*T) ... These can be implemented with just a compare and a move instruction. Do so, avoiding the overhead of a call into the runtime. These assertions are a significant cost in Go code that uses interface{} as a safe alternative to C's void* (or unsafe.Pointer), such as the current version of the Go compiler. *T here includes pointer to T but also any Go type represented as a single pointer (chan, func, map). It does not include [1]*T or struct{*int}. That requires more work in other parts of the compiler; there is a TODO.
