[Clang][AllocToken] Support TypeFuncHash and TypeFuncHashPointerSplit modes (#228492)
Extend Clang to support the `-falloc-token-mode=typefunchash` and
`-falloc-token-mode=typefunchashpointersplit` modes, which were added
to LLVM in #227686.
In these modes, CodeGen attaches the qualified name of the enclosing
function as the third operand of !alloc_token metadata. Allocations
outside functions use an empty function name. When type inference fails,
metadata is still emitted with an empty type name, so that a
function-based
token can be assigned. This allows distinguishing allocations that would
otherwise all share the fallback token.
Like the Increment and Random modes, `__builtin_infer_alloc_token()`
is not supported in constant expressions under these modes.
[lldb] Forward step plans through BorrowedStackFrame (#231657)
When a frame provider returns an index relative to its input frames,
LLDB wraps that frame in a BorrowedStackFrame. BorrowedStackFrame
forwards most StackFrame methods to the frame it borrows, except for
GetThreadPlanForStepType, so a scripted frame lost its custom step plans
as soon as another provider was stacked on top of it.
Forward it like the methods, and test stepping with a pass-through
provider stacked on top of a provider whose frames have step plans.

CI: Add an alpine3-24-kmemleak variant
Accept suffixed Alpine names in qemu-2-start.sh. For a name containing
"kmemleak", boot the linux-stable kernel with kmemleak=on and run ZTS
with -m, so each test is followed by a kmemleak scan. Run it by hand
with specific_os=alpine3-24-kmemleak.

[flang][clang][OpenMP] Fix context selector matching and scoring
Fix how OMPContext matches and scores context selectors:
- Derive device selector weights from the depth of the construct context
rather than from the candidate's construct selector count.
- Add each selector's score once, not once per property, using
arbitrary-width arithmetic instead of 64-bit sums.
- Match construct selectors as an ordered subsequence of the context and
score the highest-valued embedding. Keep partial matches for match_any.
- Apply the strict-subset rule to all applicable variants before choosing
the best one, rather than only to break ties: a selector that is a
strict subset of another compatible selector scores zero. Treat
kind(any) as an absent kind selector, and compare ISA traits by property
and name and user conditions by identity.
- Score an unknown property as unmatched instead of aborting. With two
applicable candidates, one naming an unknown vendor, Flang aborted with
"Unknown trait set is not to be used!".

[orc-rt] Describe connection specs in ogre's help. (#231665)
ogre's help described its argument only as "[positional arguments]",
though it takes exactly one connection spec, and never said what forms a
spec can take.
OptionParser gains setPositionalUsage, to name the positional arguments
in the usage line, and setEpilogue, for text printed after the options.
ogre uses them to name its <connection-spec> argument and to list the
forms it accepts. Other tools' help is unchanged.
[clang][modules] Include `-fmodule-map-file=` in context hash (#227776)
The `-fmodule-map-file=` arguments change whether headers are treated as
textual or modular. Not considering these options in the context hash
can lead to mis-compiles. This PR fixes that.

www/{nginx,nginx-devel,freenginx}: 3rd-party modules management
Build the gridfs, postgres, redis2 and sflow modules from their own
source ports instead of fetching them with GH_TUPLE.

www/nginx-module-postgres: Add New Port

PostgreSQL from nginx itself, with no application in between, and answers
with the rows as text, as JSON, or as nothing but a status code.

[LV] Have ExtractValue match the shape of the operand. (#229927)
Previously, BuildStructVector would create a vector of a wide struct
type, where each element is widened.
This can cause issues, if a transform turns an extractvalue of a wide
call into a single-scalar (e.g. makeScalarizationDecisions), because we
currently cannot extract lane 0 from a struct of vectors.
Instead of relying on BuildStructVector, we can instead have the
ExtractValue match the shape of its operand (either widen if the operand
is wide, or replicated if the operand is scalar). If a vector value is
needed, we can directly use the existing BuildVector.
This fixes a number of crashes in the newly added tests, including
https://github.com/llvm/llvm-project/issues/229609.

[libc] Order GPU targets after the generated stdint.h (#231229)
Several GPU targets reach `<stdint.h>` without depending on the
generated header, so a fresh build can compile them before or while
`stdint.h` is written and fail with `unknown type name 'uint32_t'`. This
is the same race as #149993, but via headers that don't include
`<stdint.h>` directly.
- GPU utils: `utils.h` includes `<gpuintrin.h>`, which includes
`<stdint.h>`; depend on `libc.hdr.stdint_proxy`.
- rpc_client: `shared/rpc_util.h` includes `<stdint.h>` but is also used
outside libc, so it can't use the proxy header; declare the dependency
on the libc target instead.
- GPU time_utils: declare its existing dependency on GPU utils.
This also changes GPU fixedbuffer to include `hdr/stdint_proxy.h` rather
than `<stdint.h>`. fixedbuffer was added after #150303, so it was missed
by that conversion.

ARM: Generate processor family and architecture lists in backend
ARMTargetParserDef.inc is only included by ARMSubtarget. It was
generated by the TargetParser library's tablegen step, which every
other LLVM library depends on, even when the ARM target is not
built. Generate it with the rest of the ARM backend's tablegen outputs
instead.
This removes 14% of the time in the TargetParser tablegen step, along
with a dependency on 71 ARM td files.

ip_encap: Recompute flowid for packets received over tunnel
Packets decapsulated by a tunnel interface carry the NIC's flowid
computed over the outer tunnel tuple, which is the same for every
flow a peer carries. Therefore mpath nhop selection places all
traffic on one path.
Add encap_set_flowid() to ip_encap.c, which rehashes a decapsulated
IP packet on its inner addresses.
The feature is off by default and is enabled with the per-vnet
net.route.hash_inbound sysctl.

Skip the second duplicate search when adding to an nvlist.
nvlist_add_common() removes any existing pair with the same name and
then calls nvt_add_nvpair(), which hashes the name and searches the
table for that pair again. The second search can never find anything.
Only the unpack path needs it, because it does not remove duplicates
first.
nvt_add_nvpair() now takes a flag and nvlist_add_common() skips the
search. The search also checked whether the hash table should shrink.
That check still runs on every removal.
In a perf profile of ZFS_IOC_POOL_STATS on a pool with 1200 disks the
second search was about 16% of the samples. A userland test that
builds and copies 200000 lists of 41 pairs went from about 2.42
seconds to about 2.00 seconds.
