[foreign-abi] On invokers

[Maurizio Cimadamore]

Sorry for the delay.

Here's a port of SysV of the programmable invoker. The code can be 
improved, but passes all tests (I fixed one test in TestUpcall/Downcall 
which was actually causing certain checks to be skipped, resulting in 
spurious passes, so I recommend that other patches are re-tested also). 
I also tried the support with a libclang port I have on top of the 
foreign-abi support, and everything worked reliably.

Patch here:

Cheers
Maurizio
