Title: Add Node script to generate the identifier regexes.

The script was taken from https://gist.github.com/mathiasbynens/6334847 and then modified to match Esprima’s needs.

It replaces the Python script that was previously used for the same purpose. The new script is simpler, more compact, and doesn’t require any manual post-processing of the data.
