GH-143732: SEND specialization (GH-148963)

Browse source 
* SEND specialization. Adds 2 new specialized instructions:

* SEND_VIRTUAL: for sends to virtual iterators e.g lists and tuples
* SEND_ASYNC_GEN: for sends to async generators

Tweak FOR_ITER_VIRTUAL so that SEND_VIRTUAL and FOR_ITER_VIRTUAL use equivalent guards
