DeferStmt doesnt behave as expected.

[nicolasdilley]

At the moment they are always printed at the end of the blockstmt. However, in the case of a return, they are bypassed

go func() {
defer func() { <-limitCh }()
defer wg.Done()

		path, version, agent, ok, err := isGo(pr)
		if err != nil {
			// TODO(jbd): Return a list of errors.
		}
		if !ok {
			return
		}
		found <-0
	}()

for example in this case, the return will bypass the deferstmts.
One solution is to add the deferstmts at the end of the body of the proctype being generated.
