Log:
c++-coroutines - Tidy up the builtins.

The ABI group decided not to have a mechanism for determining that a
coroutine is suspended, so remove the builtin supporting that.  We don't
use a builtin to provide the noop coroutine, so remove that.  Remove the
chunks from the library header and the testsuite.
