  Add support for running the parser generation on Mac
  
  For cloud storage, uses new bucket angle-flex-bison-mac for clarity,
  the names Linux and Mac clash.
  
  The lexer diffs seem to be due to formatter changes after the last
  generation of tjhe lexer. The diffs repro on Linux too.
  
  Lexer produces too hard to format source or diffs, and one hunk
  is left unformatted the first time. Add a workaround.

  # update_flex_bison_binaries.py:
  #   Helper script to update the version of flex and bison in cloud storage.
  #   These binaries are used to generate the ANGLE translator's lexer and parser.
  #   This script relies on flex and bison binaries to be externally built which
  #   is expected to be a rare operation. It currently only works on Windows and
  #   Linux. It also will update the hashes stored in the tree. For more info see
  #   README.md in this folder.
