- Clear ClassTokenOrOffset when setting R2R_SYSTEM_EXCEPTION flag - Add COR_ILEXCEPTION_CLAUSE_R2R_SYSTEM_EXCEPTION to R2R dumper

Encode Continuation types in R2R images using a new fixup kind (READYTORUN_FIXUP_Continuation_Layout = 0x37): - Include OwningMethod to associate the Continuation type with the correct loader allocator at runtime - Encode the GC ref map as a bit vector expanded to a byte array - Add AsyncContinuationLayoutAlgorithm for field layout computation Add runtime support to read continuation type fixups from R2R images: - GetContinuationTypeFromLayout decodes the blob and creates the type - LoadDynamicInfoEntry handles the new fixup kind Also adds helper constants for future continuation allocation helpers. Note: These code paths are not yet exercised as async2 methods are not currently compiled to ReadyToRun images.

…g unneeded method parameters and simplifying type resolution logic.

...ILCompiler.ReadyToRun/Compiler/DependencyAnalysis/ReadyToRun/ExceptionInfoLookupTableNode.cs


            foreach (MethodWithGCInfo method in _nodeFactory.EnumerateCompiledMethods())
            {
+                if (method.Method is AsyncResumptionStub)


This feels like incorrect code for now, I expect we need to be able to catch here. However, this change is already REALLY BIG. I'd prefer to see us get checked in with a set of known bugs, and iterate, than keep growing this change ever larger. I'd like a to see a bug filed about it before checkin, but its not that critical to me.

And if this is a temporary state, a ASYNC_R2R_TODO comment might be good to find these sorts of things in the codebase.

-                EcmaMethod inlinerDefinition = (EcmaMethod)inliner.GetTypicalMethodDefinition();

+                {
+                    // Async thunks are generated by crossgen and diagnostic tools don't need to worry about them


And ASYNC_R2R_TODO, verify this assumption comment probably needs to be here. We can verify after this is merged.

            }

-            if (callee.IsAsyncThunk())
+            if (callee.IsAsyncThunk() || callee.IsAsyncCall() || caller.IsAsyncThunk() || caller.IsAsyncCall())


This needs a ASYNC_R2R_TODO. In general async methods should be able to inline stuff. However, again, we should target getting this all merged, and then fixing the places where we've made suboptimal decisions.
