[clang] Consistently store format specifiers in execution encoding (#195876)

`DecomposePrintfHandler::HandlePrintfSpecifier()` parses the format
string and collects specifiers into `Specs`. In most cases the collected
specifiers are in the execution encoding, but there were to places that
used string literals in "host" encoding.

Change them to use a part of the parsed `StringLiteral` instead so that
`Specs` always contain text in the execution encoding. This is achieved
by adding `getCharacters()` method to `OptionalAmount` class, following
`ConversionSpecifier::getCharacters()`.

This is to make #169803 smaller and is an NFC before that PR lands.

[flang][cuda][openacc] Add UseDevice attribute to model host_data use_device symbols (#195182)

Symbols appearing in `!$acc host_data use_device(...)` were previously
marked with `CUDADataAttr::Device`, which caused generic resolution to
fail.

Introduce a new CUDADataAttr::UseDevice enumerator and use it in
`CopySymbolWithDevice` / `CloneDerivedTypeForUseDeviceImpl` instead of
Device. The new attribute is:

1. Compatible with any dummy in AreCompatibleCUDADataAttrs.
2. Ranked in the matching distance table (GetMatchingDistance): prefers
Device dummies (0), accepts Managed/Unified (2), and allows host dummies
(3).
3. Not user-spellable — only set internally during OpenACC name
resolution, never parsed from source or written to module files.
4. Treated like Device for non-host-array checks, I/O restrictions, and
MLIR lowering (mapped to `cuf::DataAttribute::Device`).

[clang-sycl-linker] Add per-kernel device code splitting (#195362)

Introduce a --sycl-module-split-mode option for clang-sycl-linker that
selects how the fully linked device module is split into device images:
  - none (default): one device image containing all kernels
- kernel: one device image per kernel function, built by taking the
transitive closure of each kernel's dependencies

The split is implemented by delegating to
llvm::splitModuleTransitiveFromEntryPoints, providing a categorizer that
assigns each kernel definition a unique integer id.

Symbol collection now happens during splitting while the Module is still
in memory, avoiding a round-trip through disk to re-read the bitcode for
symbol extraction.

As part of this change, the splitModuleTransitiveFromEntryPoints API is
updated to accept an Error-returning callback and propagate errors from
it, replacing the previous void callback signature. The existing caller

[NFC][VPlan] Split `makeMemOpWideningDecisions` into subpasses

The idea is to have handling of strided memory operations (either from
https://github.com/llvm/llvm-project/pull/147297 or for VPlan-based
multiversioning for unit-strided accesses) done after some mandatory
processing has been performed (e.g., some types **must** be scalarized)
but before legacy CM's decision to widen (gather/scatter) or scalarize
has been committed.

And in longer term, we can uplift all other memory widening decision to
be done here directly at VPlan level. I expect this structure would also
be beneficial for that.

[MLIR][Transform] Don't error when a structurally inlinable call exists (#195770)

Fixes bug introduced in https://github.com/llvm/llvm-project/pull/192956

Specifically transform-interpreter would crash if any op in the region
it is applied to is marked as no-inline via the inliner interface. This
is because the check added does a post processing to verify that all
operations can be inlined [and there isn't an issue due to symbol
merging]. However, it fails to account for the case where an operation
was already not inlinable (and not an error introduced by the transform
symbol merging).

[SandboxVec] SandboxVectorizerIR Boilerplate (#189515)

This patch introduces a new specialization of SandboxIR named
SandboxVectorizerIR that contains the new Pack instruction (though it is
just a placeholder for now). It also implements the necessary
boilerplate in SandboxIR to support adding such specializations.

Each specialization requires its own *Values.def file defining its new
instructions. The new .def file also needs to be added to
ValuesDefFilesList.def which allows SandboxIR to include entries from
all specializations and populate structures like the Opcode enum,
ClassID and others.

Given that we need to include both .def files in several places, I had
to (i) change the .def file to undefine its locally defined macros so
that they won't get redefined in the next #include .def, and (ii) add
the DEF_DISABLE_AUTO_UNDEF option to disable undefining the macros at
the end because otherwise the user-specified DEF_ macros would be
undefined by the time we reach the second .def file.

[AMDGPU] Implement CFI for CSR spills

Introduce new SPILL pseudos to allow CFI to be generated for only CSR
spills, and to make ISA-instruction-level accurate information.

Other targets either generate slightly incorrect information or rely on
conventions for how spills are placed within the entry block. The
approach in this change produces larger unwind tables, with the
increased size being spent on additional DW_CFA_advance_location
instructions needed to describe the unwinding accurately.
