Very few of the compiler regression tests include a comment saying waht they do. Many are obvious, some are anything but. I've started with a-c in the top directory. More will follow once we agree on the approach, correctness, and thoroughness here. zerodivide.go sneaked in too. R=rsc, r CC=golang-dev https://golang.org/cl/5656100
