Comment (by olsner):

 Since the RTS is built with `-ffunction-sections` now, the code doesn't
 need to be moved to separate files. It should be enough to remove the
 function(s) from the call graph. But that in itself might be hard enough
 :)

 BCO-related code pops up in quite a few places - e.g. `stg_AP_*` checks
 the function type and invokes `stg_yield_to_interpreter` for the `ARG_BCO`
 case, so that would still keep the interpreter alive. The generated apply
 code from genapply also has calls directly to `stg_BCO` which just yields
 to the interpreter.

 `interpretBCO` is quite little code itself though, commenting out the call
 in `schedule` saved about 15kB. Not enough to motivate much effort at all
 really...
