if self.data.len() < num_words { self.data.resize(num_words, 0) } instead?
Also needs a regression test.

Yeah, that would be nicer. I'll add the test too.

…tsakis Some preliminary work towards making trans "collector driven". The `trans::collector` already collects all translation items and `trans::partitioning` distributes these translation items into codegen units. The changes in this PR provide the following extensions to this functionality: 1. Drop-glue is handled more accurately now, knowing about the difference between `DropGlueKind::Ty` and `DropGlueKind::TyContents`. 2. The partitioning module now supports the `FixedUnitCount` strategy which more or less corresponds to the partitioning one gets via supplying `-Ccodegen-units` today. 3. The partitioning scheme also takes care of assigned LLVM declarations to codegen units, not just definitions (declarations for external items not yet implemented). It's debatable whether declarations should be handled by the partitioning scheme or whether they should just be emitted on demand.

I'll take the failed test as an opportunity to address the nits. |

Mono collector: replace pair of ints with Range I found the initial PR (rust-lang#33171) that introduced this piece of code but I didn't find any information about why a tuple was preferred over a `Range<usize>`. I'm hoping there are no technical reasons to not do this.
