Cherry Mui f187c6b08e cmd/compile/internal/pgo: check repeated edge only when node is seen 
When adding weights for a call stack, for recursive calls, to
avoid double counting we check if we already saw the node and the
edge. We check the node first. An edge can be repeated if the node
is repeated. Most stacks are not recursive, so check repeated edge
only conditionally.
