[Coroutines] Remove assert about a promise being present (#156007)

This commit removes an assert in the generation of debug info for a
coroutine frame. This assert checked if a promise alloca is present,
even though it's not used. While this might always be the case when the
coroutine was produced by clang++, this doesn't hold in the general
case.

Note: We generate coroutine intrinsics from downstream passes. In our
case, there is no guarantee that a coroutine has any promise, but they
can originate from some non-coro C++ code.
