Legacy API support for TestCafe

/*
  This is a patched version of the uglify-js@1.2.6 module.
  Added a fix for the potential Regular Expression Denial of Service
  security vulnerability: https://nodesecurity.io/advisories/48.
  The fix was copied from the commit in the UglifyJS2 repository:
  https://github.com/mishoo/UglifyJS2/commit/63d35f8f6db6d90d6142132d2d5f0bd5d3d698aa
  (see details in the issue: https://github.com/DevExpress/testcafe-legacy-api/issues/26).

  The Incorrect Handling of Non-Boolean Comparisons During Minification security
  vulnerability (https://nodesecurity.io/advisories/39) is not actual for 1.x.x versions.
