[PATCH] D102145: [Coroutines] Add `llvm.coro.align` and `llvm.coro.raw.frame.ptr.offset` intrinsics

[Yuanfang Chen via Phabricator via llvm-commits]

ychen added a comment.

- Add `llvm.coro.raw.frame.ptr.addr` to help storing raw frame address during allocation. `llvm.coro.raw.frame.ptr.offset` cannot be used during allocation because coroutine lowering would overwrite the raw frame address field with `%alloc.frame.ptr` alloca after `llvm.coro.begin`. The malloc returned address should be stored to `%alloc.frame.ptr` instead of the raw frame address field directly.
- Add tests for added intrinsics.
