Hi,

Though function co_await_expander may need to be further revised, this simple
patch fixes an ICE case in co_await_expander,

     Handle CO_AWAIT_EXPR in conversion in co_await_expander.

Function co_await_expander expands CO_AWAIT_EXPR and inserts expanded

     code before result of co_await is used, however, it doesn't cover the
     type conversion case and leads to gimplify ICE.  This patch fixes it.

Bootstrap and test on x86_64.  Is it OK?

Thanks,
