The following is my current in-progress patch (which needs tests and 
documentation, so it's quite possible some implementations are currently 
incorrect) - including all the out-of-line implementations (defined so 
that the out-of-line function implementations use the inline macro 
implementations from the header).  It doesn't attempt to use the new 
built-in functions (or, thus, to support _BitInt).  Among my notes for 
things to cover in tests include that all macros are usable inside sizeof 
etc. outside of a function (thus, do not use ({ })) - also that 
type-specific calls have the correct implicit argument conversions, also 
that both type-specific and type-generic calls evaluate arguments exactly 
once.  I haven't tested how well-optimized code is for any of these 
implementations (type-specific or type-generic) - but if it isn't, it 
probably should be, since I think all of these are among reasonable 
options for how to express the operations in terms of the underlying 
built-in functions.
