[Pipelines] Hoist CoroEarly as a module pass

[ChuanqiXu]

Summary

This change could reduce the time we call declaresCoroEarlyIntrinsics. And it is helpful for future changes.

[aeubanks]

is the fewer calls to declaresCoroEarlyIntrinsics the only reason for this change? have you measured that the calls actually take up any noticeable amount of compile time?

Oh, there are other reasons to do this change. In fact, this is a part of patch that I am working on. And I feel this part is independent and looks good to me as a separate patch. So I send it here. I didn't measure the time. But I guess it wouldn't reduce a noticeable amount of compile time.

[aeubanks]

this patch looks fine if it's part of other related work, it's just that the summary is misleading because I'm fairly certain that the compile time overhead is negligible. I'd change the summary to reflect why you actually want to do this change

Thanks! I would edit the summary when submitted.
