https://chromium.googlesource.com/chromium/blink/+/2a1c8aaf867f707ccdcd8893446e907e2aa2e1c2 This script was used to generate the old flex based CSS tokenizer. It was replaced by a custom tokenizer in r106217 but the script wasn't removed. Since there is no mention of it in the original bug nor any reference to maketokenizer in our build files, it's probably an oversight.
