b7c5ccdfe17b9cb5f7124c8d591ce0989a15b9fb by Jon Cohen <cohenjon@google.com>:

Add a shebang line and chmod +x generate_copts.py.  Note that we use the "python" command as suggested in PEP 934 (https://www.python.org/dev/peps/pep-0394/) as this script should work in both Python 2 and Python 3.

Also adds a gitignore for __pycache__ for when using python3

b3d57fcddcd737e91aab812d69b82fef2ca43d7e by Abseil Team <absl-team@google.com>:

On 32-bit systems, the alignment of int64 can be 4 bytes. Created a custom Int64 type (to go with the custom Int128 type) just for the purpose of testing layouts and alignments; it doesn't need to support actual arithmetic.
