stabilise feature(never_type)
...
Replace feature(never_type) with feature(exhaustive_patterns).
feature(exhaustive_patterns) only covers the pattern-exhaustives checks
that used to be covered by feature(never_type)

remove defaulting to unit
...
Types will no longer default to `()`, instead always defaulting to `!`.
This disables the associated warning and removes the flag from TyTuple

- `fully_normalize_associated_types_in` => `normalize_erasing_regions`
- `erase_late_bound_regions_and_normalize` => `normalize_erasing_late_bound_regions`

introduce infcx.at(..).dropck_outlives(..) operaton [VIC]
...
Backed by a canonicalized query. This computes all the types/regions that need
to be live when the destructor runs (i.e., that the dtor may access).

refactor ParamEnv::empty(Reveal) into two distinct methods
...
- `ParamEnv::empty()` -- does not reveal all, good for typeck
- `ParamEnv::reveal_all()` -- does, good for trans
- `param_env.with_reveal_all()` -- converts an existing parameter environment

Complete re-implementation of 2-phase borrows
...
See #48431 for discussion as to why this was necessary and what we hoped to
accomplish. A brief summary:
- the first implementation of 2-phase borrows was hard to limit in the way we
wanted. That is, it was too good at accepting all 2-phase borrows rather than
just autorefs =)
- Numerous diagnostic regressions were introduced by 2-phase borrow support
which were difficult to fix

mir dataflow: change graphviz output
...
The new output format is perhaps a little more readable. As a bonus, we get
labels on the outgoing edges to more easily corroborate the dataflow with the
plain MIR graphviz output.
