Sets `AlignOperands` to `DontAlign`. `clang-format` developers seem to mostly care about space-based indentation and every other version of clang-format breaks the bad mismatch of tabs and spaces that it seems to use for operand alignment. So it's better without, so that it respects our two-tabs `ContinuationIndentWidth`.
