Fix an unresolved import issue with enabled `use_extern_macros`

This is a kinda ugly special-purpose solution that will break if we suddenly add a fourth namespace, but I hope to come up with something more general if I get to import resolution refactoring this summer.

Fixes https://github.com/rust-lang/rust/issues/50187 thus removing a blocker for stabilization of `use_extern_macros`

3eadd75473 Auto merge of #50354 - varkor:initial-field-alignment-c-int, r=eddyb 
Correct initial field alignment for repr(C)/repr(int)

Fixes #50098 following https://github.com/rust-lang/rust/issues/50098#issuecomment-385497333.

(I wasn't sure which kind of test was best suited here — I picked run-pass simply because that was convenient, but if codegen is more appropriate, let me know and I'll change it.)

f5d240b432 Wrap InferCtxt::universe in a cell 
We'll need this in order to start tracking skolemizatoins here, and it's
easier to update all the field accesses now rather than later.

360cbf2f48 change skolemizations to use universe index 
This is sort of confusing "side step". All it does is to change the
representation of a skolemized region. but the source of that universe
index is not the inference context, which is what we eventually want,
but rather an internal counter in the region inference context.

We'll patch that up later. But doing this now ought to help with
confusing diffs later.

e904d56928 add universes to type inference variables 
This gives each type inference variable a notion of universe but doesn't
do anything with it. We can always get the "current universe" from
infer_ctxt. This relies on the property of type variables that they can
never interact with siblings.

Extend Printer::buf on demand.

So that 55 entries (at 48 bytes each) don't need to be eagerly
initialized on creation.

This speeds up numerous rust-perf benchmark runs, by up to 3%.

rustc: return iterators from Terminator(Kind)::successors(_mut).

Minor cleanup (and potentially speedup) prompted by @nnethercote's `SmallVec` experiments.
This PR assumes `.count()` and `.nth(i)` on `iter::Chain<option::IntoIter, slice::Iter(Mut)>` are `O(1)`, but otherwise all of the uses appear to immediately iterate through the successors.

edb8d1c0d4 Conservatively assume dropping a generator touches its upvars, via locals' dtors. 
This is meant to address rust-lang/rust#49918.

Review feedback: put back comment justifying skipping interior traversal.

Review feedback: dropck generators like trait objects: all their upvars must
outlive the generator itself, so just create a DtorckConstraint saying so.
