Alan Donovan d7287a0289 go.tool.pointer: fix regression in pointer.cgraph.Root().
The previous CL made the assumption that Root is the first
node, which is false for programs that import "reflect".
Reverted to the previous way: an explicit root field.

Added regression test (callgraph2) via oracle.
