Adding the function attribute sspreq to any function that uses ccall might help with more quickly identifying stack corruption coming from external libraries.

We could just add this with an ifdef, and later (or immediately) as a command line switch. Feel free to add it in any way that's off by default.

I would, but I don't know how to find the *Function for the function currently being JIT'd from within emit_ccall.
