[flang][OpenMP] Lower target in_reduction
Enable host lowering for target in_reduction in Flang and MLIR OpenMP
translation.
Model target in_reduction through the matching map entry, force
address-preserving implicit mapping for Flang in_reduction list items, and emit
the host-side task-reduction lookup with __kmpc_task_reduction_get_th_data. The
runtime entry point takes and returns a generic, default-address-space pointer,
so normalize a non-default-address-space captured pointer to the generic address
space before the call and cast the returned private pointer back to the map
block argument's address space, mirroring the in_reduction handling on
omp.taskloop. On the target device, in_reduction is handled as a regular
map(tofrom) variable. The byref modifier, two-argument initializers, cleanup
regions, and the remaining Flang COMMON/EQUIVALENCE/privatized-variable cases
continue to be diagnosed.
Add Flang lowering, MLIR verifier/translation, and LLVM IR tests for the
supported host path, including a non-default-address-space case, and the
remaining unsupported cases.
[SampleProfile] Remove ProfileHasAttribute parameter from readFuncMetadata (NFC) (#208604)
This patch removes the ProfileHasAttribute parameter from
readFuncMetadata overloads.
Because ProfileHasAttribute is set once in readImpl during section
header parsing and never modified afterward, readFuncMetadata observes
the exact same immutable value regardless of whether it is passed as a
function parameter or read from the class member variable.

[CodeGen] Teach ReplaceWithVeclib split vector llvm.sincos when only sin/cos veclib mappings exist (#194639)
Some vector math libraries provide vector sin and vector cos but no
vector sincos or no sincos with an ABI that LLVM can emit.
The one of the common case is glibc libmvec on x86: it exposes
`_ZGV{b,c,d,e}N{2,4,8,16}vvv_sincos{,f}` symbols, but those use a
vectors-of-pointers output ABI that expandMultipleResultFPLibCall does
not currently support. As a result, sincos will falls back to scalar
sincos calls even when the target has a fully working vector sin and
vector cos.
So we trying to split it into separate sin and cos calls, which will
then be replaced with vector calls if the target supports it, it
generally better than scalarized sincos calls.
[CycleInfo] Store blocks using Euler tour representation (#208614)
Each GenericCycle owned a `SetVector<BlockT*>` of its blocks (its own
plus every nested cycle's), so a block nested D cycles deep is stored D
times.
Instead, store every cycle's blocks in one GenericCycleInfo::BlockLayout
array laid out as an Euler tour of the cycle forest: each cycle owns a
contiguous range [IdxBegin, IdxEnd) nested inside its parent's.
run() builds the cycle tree and the block-to-innermost-cycle map as
before, then lays the array out in `layoutBlocks`. Its DFS also moves
from a single worklist that eagerly pushed every successor (so the stack
grew with the fan-out along the current path) to a stack of (block,
successor cursor) frames bounded by the DFS depth, with each block
pushed once; successors are still visited in the same order (hence the
weird `std::reverse_iterator`), so the cycles found are unchanged.
Block iteration order within a cycle changes, so cycle-print order in

[RISCV] Rename VLSU_MEM_LATENCY to Andes45VLSU_MEM_LATENCY in RISCVSchedAndes45.td (#209388)
Prefix the defvar with the Andes45 scheduler name to match the other
Andes45-local defvars (e.g. Andes45DLEN) and avoid a bare, generic name
in the shared RISC-V TableGen namespace.

[lit] Remove most external shell test coverage
Now that LLVM 23 has branched, we can look at removing the external
shell.
https://discourse.llvm.org/t/rfc-removal-of-the-lit-external-shell/90951
This patch removes most test coverage that was explicitly for the
external shell as it was entirely duplicated with the internal shell.
This patch leaves out removing test coverage in shtest-format as not all
the coverage there is duplicated and it seems like there is some missing
from the internal shell and I want to give it more careful
consideration.

[CIR] Fix x86 builtin tests after tighter inlining (#209653)
The behavior of the AlwaysInliner was tightened in a recent change
(https://github.com/llvm/llvm-project/pull/209345) to avoid inling
functions with mismatched target attributes even when the alwaysinline
attribute was present. This exposed a few failures in CIR where we were
either running with stale target features or missing target features
that were needed for the builtins we were testing.
This change updates the run lines to use the correct feature sets.
