clang-format: Update to clang-format >= 6

We get new interesting formating with clang-format greater or equal to 6
as stated in the removed comments.  Miguel Ojeda suggested to even move
the minimal clang-format version to 11, which is the minimum LLVM
supported at the moment [1].

Automatically updated with:
sed -i 's/^\(\s*\)#\(\S*\s\+\S*\) # Unknown to clang-format.*/\1\2/' .clang-format
