Thanks. I don't have a strong opinion here. The main downside to forcing static linking here is that we spend more time linking and take up more space. cc @rnk 

By the way, I think for FileCheck, we should exclude that components from the dylib entirely -- it's only used by FileCheck, and utilities are always statically linked. So static linking for that test makes sense.
