Detailed Description

Find a SuspendsExpr's in a coroutine body statement for early transformation.

Traverse the whole CoroutineBodyStmt to find all appearing VarDecl. These need to be rerouted to the coroutine frame and hence prefixed by something like __f->. For that reason we only look for VarDecls directly appearing in the body, CallExpr will be skipped.
