cast a struct sockaddr * to typedef of struct sockaddr_bird * (which is
just a padded sockaddr *), the subsequent address extraction (involving
a bit of indirection) doesn't touch the bytes of padding, removes warning
seen with llvm19 which becomes an error

[LifetimeSafety] Fix false negative for GSL Owner methods inherited from a non-Owner base (#197864)
- Take the implicit object's actual type (e.g., the type before any
`DerivedToBase` cast) into account when checking for GSL Owner. Other
`isGslOwnerType` call sites with the same pattern (e.g.,
`isGslOwnerType(MCE->getImplicitObjectArgument()->getType())` in
`VisitCXXMemberCallExpr`) lack a real-world trigger today and are
deferred to a follow-up.
- Unify the GSL Owner checks inside `shouldTrackImplicitObjectArg` so
they share a single source of truth.

[VPlan] Collect FOR PHIs before sinking/hoisting recurrence users (#194671)
Avoid iterating over HeaderVPBB->phis() while potentially mutating the
underlying VPBasicBlock. Collect all VPFirstOrderRecurrencePHIRecipe
instances first, then process them in a separate loop.
This prevents iterator invalidation when sinking or hoisting recurrence
users, and makes the transformation more robust.

[LV] Move constant folding test to VPlan (NFC). (#198407)
Check VPlan print for constant folding test. This makes it more robust
w.r.t. to future cost-modeling changes.
[VPlan] Collect unit-stride predicates for making vector decisions. (#199568)
Split-off from approved https://github.com/llvm/llvm-project/pull/197276
to land separately.
Collect all unit-stride predicates once, up-front, ensuring that cost
decisions have predicates available, independent of processing order.
hwpmc: Avoid panic on AMD cpus where IBS is not available
The recent IBS work intruduced a bug on older CPUs where the
IBS handler will be called on NMIs even when IBS is not initialized.
Work around this in the IBS handler by checking to see if ibs_pcpu
is NULL before accessing it.
Improve system dataset moves
* Use FD-based mount APIs for moving around system datasets
* Use zfs send/recv for shifting system datasets between pools
* Use mounting beneath + unmounting on top combined with
stopping / starting services to ensure that we're as close as
possible to being atomic with these moves.
sys/uvm/pdaemon: compare constraints in paddr units
uvm_constraint_range bounds are physical addresses, as is
VM_PAGE_TO_PHYS(). Do not apply atop() before comparing them, otherwise
the pagedaemon matches page frame numbers against byte address ranges.
