Regression introduced by "remove fork analysis from tail call optimization (ref #86)"

[wader]

Hi, the commit c08e56f seems to have introduced a regression:

test.jq

def f:
  if .a then .a | f
  else .
  end;

{
  "a": {
    "b": {
      "c": 1
    }
  }
} | f | 2

jq 1.6

$ jq -nf test.jq
2

gojq master (58fe974):

$ go run cmd/gojq/main.go -nf test.jq
{
  "b": {
    "c": 1
  }
}

gojq c08e56f~1

$ go run cmd/gojq/main.go -nf test.jq
2
