[Coro] Allow spilling @llvm.coro.suspend() to the coro frame (#133088 )

It was excluded from spilling in a263a60, possibly by accident.

In the linked bug, we hit a situation like this:

```
  %s = call @llvm.coro.suspend(...)
             |
       switch (%s)
case v1: /       \ case v2:
        ...      ...
         |       suspend point
         |       ...
         \       /
 %x = phi [v1] [v2]
             |
            ...
             |
         use(%x)
```

Instcombine will notice that %x correlates exactly with %s, and so
use(%x) becomes use(%s).

However, corosplit would substitute different values for %s when
splitting the function, so even though %s had a particular value when
control actually passed through the switch, it could have a *different*
value when reaching use(%s).

This illustrates that while IR from the frontend typically does not use
these suspend return values across suspend points, mid-level
optimizations on the presplit coroutine may introduce new uses of
suspend values, so they must be considered eligible to spill to the
coroutine frame.

Fixes: #130326
