This paper adds 'i' and 'j' as suffixes for forming a _Complex constant. This feature has been supported in Clang since at least Clang 3.0, so only test coverage is needed. It does remove -Wgnu-imaginary-constant in C mode (still used in C++ mode) because the feature is now a C2y feature rather than a GNU one.
