  Log Message:
  -----------
  [LoopInfo] Pointer to stack object may not be loop invariant in a coroutine function (#149936)

A coroutine function may be split to ramp function and resume function,
and they have different stack frames, so a pointer to stack objects may
have different addresses depending on where it is used, so it's not a
loop invariant.

It temporarily fixes https://github.com/llvm/llvm-project/issues/149604.
