The special case logic for go/defer arguments in Escape.call was scattered around a bit and was somewhat inconsistently handled across different types of function calls and parameters. This CL pulls the logic out into a separate callStmt method that's used uniformly for all kinds of function calls and arguments. Fixes #31573.
