I downloaded https://docs.google.com/spreadsheets/d/15az3FMl-jAS0mx4E9XVSBVHVpmEzo-9EAGY0ywe7bZs/edit#gid=0
as a csv file, and removed the header line and all columns except the filename.
Then i ran this script to create this CL:

    import os, re, subprocess
    edits = {}
    for filename in open('/Users/thakis/Downloads/files.txt'):
      filename = filename.strip()
      if not filename.endswith('.h'):
	continue
      basename = os.path.basename(filename)
      cc = r'\b' + os.path.splitext(basename)[0] + r'\.(cc|cpp|mm)\b'
      p = subprocess.Popen(['git', 'grep', '-En', cc, '--', '*.gn', '*.gni'],
			   stdout = subprocess.PIPE)
      out, _ = p.communicate()
      if p.returncode != 0 or not out:
	continue

      for gnline in out.splitlines():
	gnfile, linenr, contents = gnline.split(':')
	linenr = int(linenr)
	new = re.sub(cc, basename, contents)
	print gnfile, linenr, new
	edits.setdefault(gnfile, {})[lin...
