  [Coroutines] Use default attributes for some coro intrinsics

This adds the default attributes (nosync, nofree, nocallback,
willreturn) to the coro.id and coro.subfn.addr intrinsics. This
is needed to avoid optimization regressions in the future.

It's probably possible to use default attributes for most other
coro intrinsics as well, but I only hit these as problematic in
practice.
