clang-format: Adapt line break penalties for LLVM style.

Specifically make clang-format less eager to break after the opening
parenthesis of a function call.

Before:
  aaaaaaaaaaaaaaaaa(
      aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa + aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa,
      aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa);

After:
  aaaaaaaaaaaaaaaaa(aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa +
                        aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa,
                    aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa);

Apparently that is preferable. This penalties are adapted
conservatively, we might have to increase them a little bit further.
