[PATCH] D74677: [bugpoint] Also replace declarations with null.

This revision now requires changes to proceed.

Calling null is (I think) full out UB.  This may be a more hostile reduction strategy than is warranted.  It's likely to result in extremely unstable reductions.

An alternative would be to pick a canonical callee (non-null declaration) and map all calls of a given signature to the same decl.

Also, I'm not opposed to this version if you really want, just pointing out a possible downside.
