Check recursion limit in VisitorLevelSpecification

[tranleduy2000]

Check recursion limit in VisitorLevelSpecification instead of relying on Java's StackOverflowError.

The current implementation may not work, JVM may kill the process when StackOverflowError occurs.

interface IAST {
  default IExpr acceptChecked(IVisitor visitor) {
    try {
      return accept(visitor);
    } catch (StackOverflowError soe) {
      RecursionLimitExceeded.throwIt(Integer.MAX_VALUE, this);
    }
    return F.NIL;
  }
}
