[PATCH] D22659: [coroutines] Part 2 of N: Adding Coroutine Intrinsics

[Gor Nishanov via llvm-commits]

GorNishanov updated this revision to Diff 65471.
GorNishanov added a comment.

Documentation updated to state that coro.alloc is required to have heap allocation elision.
Intrinsics attributes tweaked:
coro.alloc is now [], (when it was IntrNoMem, multiple coro.allocs belonging to different coroutines were coalesced into one, breaking the semantics)
coro.begin is now capturing the promise parameter, otherwise, GVN won't recognize operations that may write to the promise.
