There are several changes to the load/store helpers coming, and making
sure that those changes are properly reflected across all of the backends
was harrowing.
I have gone back and restarted by hoisting the code out of the backends
and into tcg.c. We already have all of the parameters for the host
function call abi for "normal" helpers, we simply need to apply that to
the load/store slow path.
No major changes for v4. A few patches upstreamed, and one new one
based on Phil's review.
