cmd/compile/internal/syntax: expose additional information for gc
gc needs access to line offsets for Nodes. It also needs access to the end line offset for function bodies so it knows what line number to use for things like implicit returns and defer executions. Lastly, include an extra bool to distinguish between simple and full slice expressions. This is redundant in valid parse trees, but needed by gc for producing complete warnings in invalid inputs.
