Re-run clang-format with InsertBraces.

This CL runs the same command as in the preceding CL, but with
'IncludeBraces: true' added to .clang-format. I've split this out
separately because the documentation says:

> Setting this option to true could lead to incorrect code formatting
> due to clang-format’s lack of complete semantic information. As such,
> extra care should be taken to review code changes made by this option.

I've also kept InsertBraces out of .clang-format for now because it's a
fairly recent option, and clang-format fails when it sees unrecognized
options.
