[LoopInterchange] Reject interchange when a freeze would move or be cloned

Loop interchange moves four blocks to a different loop depth: the outer loop
header and latch, and the inner loop preheader and exit block. It also splits
the inner loop latch and clones the instructions that compute the latch branch
condition and induction variable updates into the new latch block.

LangRef guarantees that all uses of the value returned by one execution of a
`freeze` observe that same value. The guarantee does not extend across
executions, so one `freeze` may yield a different value each time it runs.
Different `freeze` instructions may also yield different values for the same
`undef` or poison operand. Both steps above can therefore change which value a
use observes.

Moving a `freeze` to a different loop depth changes which loop iterations share
one dynamic result. Uses that observed a single frozen value in the original
nest can observe values from separate executions after interchange. Cloning a
`freeze` creates a second, independent instruction, so the original and clone
can yield different values for the same operand.

Reject the interchange when a `freeze` appears in one of the four moved blocks
or among the instructions cloned into the new latch. A `freeze` elsewhere still
reaches the same uses from each execution, so it remains allowed. That includes
a `freeze` in the outer loop preheader and one in the inner loop body outside
the cloned computations. The check is conservative and does not try to prove
that the operand of a `freeze` is never `undef` or poison.

[HLSL] Consistently quote resource attribute args (#214106)

The `hlsl::resource_class` and `hlsl::dimension` attributes both take a
single argument from a set of choices, but resource_class expects an
unevaluated identifier and dimension expects a string literal.
Consistently require the literal for both, and fix up the AST printers
to match.

[LoongArch][MC] Pre-mark align fragments as linker-relaxable (#213582)

Extract `shouldRelaxAlign` from `relaxAlign` and call it during
`emitCodeAlignment` to eagerly set the linker-relaxable flag on align
fragments. This ensures `isRangeRelaxable` returns correct results
before the layout phase.

[ELF][AArch64] Do not treat missing build attributes as defined (#213600)

Even if an AArch64 build attributes section contains only private
subsections and does not define feature flags or PAuth information,
`lld` still checks the values defined in the GNU Program Properties
section against the build attribute defaults, producing warnings and
errors. The patch adjusts the handling of build attributes so that only
the existing attributes are used.

[NPM] Make few more passes required - 2 (#213608)

as discussed in https://github.com/llvm/llvm-project/pull/203511, few of
these should not really be required (such as sink) with O0/opt-none, yet
we require this for consistency between legacy and NPM. We need to look
at the passes separately and selectively make strictly optimizing passes
optional.

[CIR][SYCL] Support SYCL kernel call statement in host codegen (#213728)

Add CIRGen support for lowering SYCLKernelCallStmt during host
compilation, emitting the kernel launch statement in place of the
`sycl_kernel_entry_point` function body (mirroring classic CodeGen). 

Device compilation, were the offload kernel caller entry point
is emitted instead, is future work and thus marked as NIY.

[flang][cuda] Delay box cuf.alloc past host association captures (#214347)

CUFAllocDelay treated the store of a descriptor into a host association
tuple as a use, so a device allocatable captured by an internal
procedure kept its descriptor allocation in the prologue. That allocates
managed memory before the program can call cudaSetDevice, binding a CUDA
context to the wrong device.

The store now sinks together with the allocation, constrained by the
tuple's readers, and the group is placed at the nearest common dominator
of all uses so it can sink into a later block.

[AMDGPU][GlobalISel] Pre-commit tests for readanylane merge regbank combine (NFC)

Add regbank-combiner tests covering a copy to vgpr whose source is a
merge or build_vector of G_AMDGPU_READANYLANE results and uniform
values. These currently keep the round trip through sgprs, and also
cover the cases where the merge has another user and where all merge
sources are uniform.
