Remove OpenSnapshot
and CommittedSnapshot
markers from SnapshotMap
.
...
They're not strictly necessary, and they result in the `Vec` being
allocated even for the trivial (and common) case where a
`start_snapshot` is immediately followed by a `commit` or `rollback_to`.

Introduce in_snapshot
and assert_open_snapshot
methods.
...
This makes the two snapshot implementations more consistent with each
other and with crate `ena`.

Make commit
and rollback_to
methods take ownership of the snapshots.
...
Because they shouldn't be reused. This provides consistency with the
`ena` crate.

Rename UndoLogEntry
as UndoLog
.
...
So that it matches `librustc_data_structures/snapshot_map/mod.rs` and
the `ena` crate.

Remove insert_noop
.
...
Because it's as useless as its name suggests.
This commit also renames `UndoLog::Noop` as `UndoLog::Purged`, because
(a) that's a more descriptive name and (b) it matches the name used in
similar code in `librustc/infer/region_constraints/mod.rs`.

Update to ena
0.11.0.

Cleanup from lexical MIR borrowck removal
Lexical MIR borrowck was removed months ago now, and `EndRegion`s are no longer used for MIRI verification.
* Remove `rustc::mir::StatementKind::EndRegion` and the `-Zemit_end_regions` flag
* Use `RegionVid` instead of `Region` in BorrowSet
* Rewrite drop generation to create fewer goto terminators.

[Windows] Work around non-monotonic clocks in the self-profiler
...
On Windows, the high-resolution timestamp api doesn't seem to always be
monotonic. This can cause panics when the self-profiler uses the
`Instant` api to find elapsed time.
Work around this by detecting the case where now is less than the start
time and just use 0 elapsed ticks as the measurement.
Fixes #51648
