--- The @GRAN_YIELD@ macro is taken from JSM's  code for Concurrent Haskell. It
--- allows to context-switch at  places where @node@ is  not alive (it uses the
--- @Continue@ rather  than the @EnterNodeCode@  function in the  RTS). We emit
--- this kind of macro at the beginning of the following kinds of basic bocks:
--- \begin{itemize}
---  \item Slow entry code where node is not alive (see @CgClosure.lhs@). Normally 
---        we use @fetchAndReschedule@ at a slow entry code.
---  \item Fast entry code (see @CgClosure.lhs@).
---  \item Alternatives in case expressions (@CLabelledCode@ structures), provided
---        that they are not inlined (see @CgCases.lhs@). These alternatives will 
---        be turned into separate functions.
