[CIR][NFC] Convert MissingFeatures::requiresCleanups to errorNYI (#192350)
This change adds errorNYI calls in two places that we previously had
requiresCleanups() missing features markers, adds a more specific
missing feature marker for loops, removes one requiresCleanups() where
the handling was already implemented, and deletes a bunch of missing
feature markers there were never used.
[BOLT][Passes] use ADT containers for instrumentation spanning tree. (#192289)
Swap `std::unordered_map<…, std::set<…>>` for

per-set heap allocations, stops inserting empty buckets on every probe,
and replaces linear `is_contained()` scans over a red-black tree with
linear scans over inline `SmallVector` storage (most basic blocks have
at most a couple of spanning-tree out-edges). NFC.

Fix read corruption after block clone after truncate
When copy_file_range overwrites a recent truncation, subsequent reads
can incorrectly determine that it is read hole instead of reading the
cloned blocks.
This can happen when the following conditions are met:
- Truncate adds blkid to dn_free_ranges
- A new TXG is created
- copy_file_range calls dmu_brt_clone which override the block pointer
and set DB_NOFILL
- Subsequent read, given DB_NOFILL, hits dbuf_read_impl and
dbuf_read_hole
- dbuf_read_hole calls dnode_block_freed, which returns TRUE because the
truncated blkids are still in dn_free_ranges
This will not happen if the clone and truncate are in the same TXG,
because the block clone would update the current TXG's dn_free_ranges,
which is why this bug only triggers under high IO load (such as

Use AVL tree lookup in zfsctl_snapdir_vget for mounted snapshots
zfsctl_snapdir_vget resolves NFS file handles for snapshot directory
entries by calling zfsctl_snapshot_path_objset, which iterates all
snapshots via dmu_snapshot_list_next to find the matching objsetid.
With many snapshots this linear scan is expensive.
For snapshots that have been previously mounted, the path is already
cached in the in-memory AVL tree. Check the tree first with
zfsctl_snapshot_find_by_objsetid and fall back to the on-disk scan
only when the entry is not found.

draid: fix cksum errors after rebuild with degraded disks
Currently, when more than nparity disks get faulted during the
rebuild, only first nparity disks would go to faulted state, and
all the remaining disks would go to degraded state. When a hot
spare is attached to that degraded disk for rebuild creating the
spare mirror, only that hot spare is getting rebuilt, but not the
degraded device. So when later during scrub some other attached
draid spare happens to map to that spare, it will end up with
cksum error.
Moreover, if the user clears the degraded disk from errors, the
data won't be resilvered to it, hot spare will be detached almost
immediately and the data that was resilvered only to it will be
lost.
Solution: write to all mirrored devices during rebuild, similar
to traditional/healing resilvering, but only if we can verify
the integrity of the data, or when it's the draid spare we are
