ls is certainly *not* a builtin.  It comes from GNU coreutils:

mbt at aloe:~$ ls --version
ls (GNU coreutils) 8.5

cd has always been a built-in (as it must be due to its behavior).
echo, printf, and test have been built-ins in bash for quite some time,
though (there are binaries available for them for older shells that do
not have them built-in).
