[clang] Backport: fix transformation of substituted constant template parameters of partial specializations
This fixes a helper so it implements retrieval of the argument replaced
for a template parameter for partial spcializations.
This was left out of the original patch, since it's quite hard to actually test.
This helper implements the retrieval for variable templates, but only for
completeness sake, as no current users rely on this, and I don't think a similar
test case is possible to implement with variable templates.
This fixes a regression introduced in #161029 which will be backported to llvm-22,
so there are no release notes.

[clang] Backport: allow canonicalizing assumed template names
Assumed template names are part of error recovery and encode just a
declaration name, making them always canonical. This patch allows
them to be canonicalized, which is trivial.

Fixes #183075
[clang] Backport: NestedNameSpecifier typo correction fix
This stops typo correction from considering template parameters
as candidates for a NestedNameSpecifier when it has a prefix itself.
I think this is better than the alternative of accepting these candidates,
but otherwise droping the prefix, because it seems more far-fetched that
someone would actually try to refer to a template parameter this way.
Since this regression was never released, there are no release notes.

Fixes #167120
[clang] Backport: stop error recovery in SFINAE for narrowing in converted constant expressions
A narrowing conversion in a converted constant expression should produce an
invalid expression so that [temp.deduct.general]p7 is satisfied, by stopping
substitution at this point.
Fixes #167709
[clang] create local instantiation scope for matching template template parameters
This fixes a bug where a partial substitution from the enclosing scope
is used to prepopulate an unrelated template argument deduction.

[analyzer] Fix crash in MallocChecker when a function has both ownership_returns and ownership_takes (#183583)
When a function was annotated with both `ownership_returns` and
`ownership_takes` (or `ownership_holds`), MallocChecker::evalCall would
fall into the freeing-only branch (isFreeingOwnershipAttrCall) and call
checkOwnershipAttr without first calling MallocBindRetVal. That meant no
heap symbol had been conjured for the return value, so
checkOwnershipAttr later dereferenced a null/invalid symbol and crashed.
Fix: merge the two dispatch branches so that MallocBindRetVal is always
called first whenever ownership_returns is present, regardless of
whether the function also carries ownership_takes/ownership_holds.
The crash was introduced in #106081
339282d49f5310a2837da45c0ccc19da15675554.
Released in clang-20, and crashing ever since.
Fixes #183344.

devel/lua-cjson/openresty: [NEW PORT]
Fast JSON encoding/parsing for Lua with OpenResty enhancements
This fork of mpx/lua-cjson is included in the OpenResty bundle and includes
a few bugfixes and improvements, especially to facilitate the encoding of
empty tables as JSON Arrays.
Please refer to the lua-cjson documentation for standard usage.

[Clang] Don't diagnose missing members when looking at the instantiating class template
This backports https://github.com/llvm/llvm-project/pull/180725 to Clang
22.
The perfect matching patch revealed another bug where recursive
instantiations could lead to the escape of SFINAE errors, as shown in
the issue.
RISCVMCAsmInfo: Remove redundant `UseAtForSpecifier = false`. NFC (#183890)
UseAtForSpecifier defaults to false in MCAsmInfo, and RISCVMCAsmInfo
never calls initializeAtSpecifiers (which sets it to true).
[Hexagon] Fix extractHvxSubvectorPred shuffle mask for small predicates (#181364)
The loop generating the shuffle mask in extractHvxSubvectorPred used
HwLen/ResLen as the iteration count, but each iteration produces 8
elements (ResLen * Rep where Rep = 8/ResLen). This means the total mask
size was (HwLen/ResLen) * 8, which only equals HwLen when ResLen == 8.
For smaller predicate subvectors (e.g., <4 x i1> or <2 x i1>), the mask
was too large, causing an assertion failure in getVectorShuffle.
Fix by using HwLen/8 as the loop bound, which correctly produces HwLen
elements regardless of ResLen.

[mlir][IR] Generalize `DenseElementsAttr` to custom element types (#179122)
`DenseElementsAttr` supports only a hard-coded list of element types:
`int`, `index`, `float`, `complex`. This commit generalizes the
`DenseElementsAttr` infrastructure: it now supports arbitrary element
types, as long as they implement the new `DenseElementTypeInterface`.
The `DenseElementTypeInterface` has the following helper functions:
- `getDenseElementBitSize`: Query the size of an element in bits. (When
storing an element in memory, each element is padded to a full byte.
This is an existing limitation of the `DenseElementsAttr`; with an
exception for `i1`.)
- `convertToAttribute`: Attribute factory / deserializer. Converts bytes
into an MLIR attribute. The attribute provides the assembly format /
printer for a single element.
- `convertFromAttribute`: Serializer. Converts an MLIR attribute into
bytes.
Note: `convertToAttribute` / `convertFromAttribute` are mainly for
