[Piglit] [PATCH 03/24] gen_shader_bit_encoding_test.py: use the if __name__ == __main__ pattern

[Dylan Baker]

v2: - replace gen_shader_bit_encoding: cleanup some styles issues with
      this patch
    - leaves the camel case function names alone (matt, ilia)
    - leaves block comment in test_data
