For the bit rotations the situation is even worse (see Issue 5728 and Issue
6829 ), because in Phobos we don't even have the function that contains the
recognized pattern, so it's kind of easy for programmers to write the pattern
wrong or for compilers to miss the pattern. (Currently both dmd and ldc2 don't
recognize some rotations.)
