-// Reduce a ufuzz-style `console.log` based test case by iteratively replacing

-// tree and the last known good tree produce the same non-nil error-free output

-// This function assumes that the testcase will not result in a parse or
-// runtime Error.  Note that a reduced test case will have different runtime
-// output - it is not functionally equivalent to the original. The only criteria
-// is that once the generated reduced test case is run without minification, it
-// will produce different output from the code minified with `minify_options`.
