[SLP] Loop aware cost model/tree building
Currently, SLP vectorizer do not care about loops and their trip count.
It may lead to inefficient vectorization in some cases. Patch adds loop
nest-aware tree building and cost estimation.
When it comes to tree building, it now checks that tree do not span
across different loop nests. The nodes from other loop nests are
immediate buildvector nodes.
The cost model adds the knowledge about loop trip count. If it is
unknown, the default value is used, controlled by the
-slp-cost-loop-min-trip-count=<value> option. The cost of the vector
nodes in the loop is multiplied by the number of iteration (trip count),
because each vector node will be executed the trip count number of
times. This allows better cost estimation.

libspl/mnttab: remove struct extmnttab
The two additional fields are never used by calling code, and we can
replace their sole internal use with an extra stack param.

libzfs/mnttab: always enable the cache
There's no real reason not to enable it always; the `zfs` command always
enables it anyway, and right now there's multiple places that do mount
work that don't go through the cache anyway. Having it always be on lets
us remove a bunch of the fallback code.

Add tiering API
This commit modifies the truenas API to wrap around tiering design
in the following ways:
A new namespace zfs.tier. will be added. This contains global
configuration for systemwide tiering settings. Parameters include
- enabled: whether to enable tiering. This feature requries changes
to global ZFS behavior and we will have various internal checks
that check this value in datastore extend context methods.
- max_concurrent_jobs: the maximum number of concurrent rewrite
jobs (tier migrations for existing data).
- min_available_space: point in available space for a dataset where
tier migrations will error out.
The namespace will also support APIs for managing and querying

[CIR] Add abstract delete operation without AST attribute (#185538)
This introduces the cir.delete_array operation, adds code to emit that
operation during CIR codegen, and adds lowering of the operation to the
CXXABILowering pass.
In order to handle possible variations in the delete representation, we
add the name of the delete function, the usual delete parameters, and,
optionally, the name of the element destructor function.
During the CXXABILoweringPass, the cir.delete_array operation is
expanded to call the delete function. This will be extended in a future
change to handle reading the array cookie, if required, and calling
element destructors.
[SystemZ][GOFF] Reference to external variable needs PR symbol
Variables are modelled as parts in the GOFF format. Referencing a

A small issue is that these PR symbols can refer to the same ED
symbols, for which a section needs to be created.

ena: Verify that an ENA ring is in netmap only in native mode
netmap operates in two modes:
1) Emulated - netmap handling is done by the network stack, the
NIC driver operates transparently to netmap.
2) Native - netmap management is done by the NIC driver.
When checking whether a specific ENA ring is running in netmap
mode, only the following checks were done:
1. IFCAP_NETMAP - Check whether netmap capability is enabled on
the device.
2. NKR_NETMAP_ON - Check whether netmap is actively using this
ring.
The above checks implied that the netmap mode is native and the
ENA driver needs to handle the netmap logic.
The code was missing an explicit check on whether native mode
is actually on (NAF_NATIVE).
This led to a case where though emulated mode was used and
