Revert "[clang-format] Fix putting ObjC message arguments in one line for multiline receiver"
This reverts commit db9e5e9a616d7fdd4d1ba4c3b2cd89d8a0238533 (rC333171).
Mentioned change introduced unintended formatting of ObjC code due to split priorities inherited from C/C++, e.g.:
fooooooo = [ [obj fooo] aaa:42 aaa:42];
fooooooo = [[obj fooo] aaa:42 aaa:42];
when formatted with ColumnLimit = 30.
