[PATCH v2 5/8] clang-format: avoid braces on simple single-statement bodies

[Karthik Nayak <karthik.188@gmail.com>]

Set the 'RemoveBracesLLVM' to 'true' which ensures that we avoid curly
braces for single-statement bodies in conditional blocks.

This option does come with two warnings:

    This option will be renamed and expanded to support other styles.

and

    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.

The latter seems to be of concern. But since we only use clang-format to
verify the format and not to apply formatting, we should be okay here.
