clang-format: Increase cut-off limit for number of analyzed states.

With more complex structures in C++ Lambdas and JavaScript function
literals, the old value was simply to small. However, this is a
temporary solution, I need to look at this more closely a) to find a
fundamentally better approach and b) to look at whether the more recent
usage of NoLineBreak makes us visit stuff in an unfortunate order
where clang-format waste many states in dead ends.
