Sparse can do constant folding of __builtin_bswap*() since 2017. Also, a much recent version of Sparse is needed anyway, see commit 6ec4476ac825 ("Raise gcc version requirement to 4.9").
So, remove the comment about sparse not being yet able to constant fold __builtin_bswap*() and remove the corresponding test of __CHECKER__.
