![]() Fix `ByMove` coroutine-closure shim (for 2021 precise closure capturing behavior) This PR reworks the way that we perform the `ByMove` coroutine-closure shim to account for the fact that the upvars of the outer coroutine-closure and the inner coroutine might not line up due to edition-2021 closure capture rules changes. Specifically, the number of upvars may differ *and/or* the inner coroutine may have additional projections applied to an upvar. This PR reworks the information we pass into the `ByMoveBody` MIR visitor to account for both of these facts. I tried to leave comments explaining exactly what everything is doing, but let me know if you have questions. r? oli-obk |
