PING! [3/4] [patch, middle-end] Make native_encode/interpret_expr non-static.

[Brooks Moses <bmoses at stanford dot edu>]

:ADDPATCH middle-end:

Ping?  (As noted in 2/4, I know this is a touch early for a ping, but I 
also need to add it to the tracker, and manual adding doesn't work.)

Thanks,
- Brooks
