passes: add a backend pass to insert a sentinel value to exception table

To determine if a function is a Go function, we insert a sentinel
value to the function's exception table. The runtime will check
the existence of this value (see CL 140518 for the runtime part).

Add "passes" directory, a place to put LLVM backend passes.
