If we do decide it is worth avoiding calls to 'memcpy' for small sizes,
please don't put the expanded code in-line at the points of use, because
that obscures the functional purpose of the code. Instead, put the
optimised version in a suitably named local function ("fast_memcpy"?) so
that the main function remains easy to read.
