[X86] combineINSERT_SUBVECTOR - enable shuffle combining of concat(extractsub(shuffle),extractsub(shuffle)) patterns (#209510)
Reuse the peekThroughBitcastsAndExtracts helper that we already use for insertsub(shuffle,extractsub(shuffle)) patterns
[lldb-server] Add type info for qMemoryinfo reponse (#209235)
Use the name of the memory region to report the known cases where an
address points to stack/heap: "[stack]" or "[heap"].
According to [1], the "[stack]" name is the main thread's stack region:
```
[stack]
The initial process's (also known as the main
thread's) stack.
```
For other threads, we can't know their stack region because this field
got removed in newer kernels:
```
[stack:tid] (from Linux 3.4 to Linux 4.4)
A thread's stack (where the tid is a thread ID). It
corresponds to the /proc/pid/task/tid/ path. This

AMDGPU: Migrate CodeGen tests to amdgpu subarch triple (34) (#209598)
Mechanically migrate the command-line target spelling on llc/opt RUN
lines in llvm/test/CodeGen/AMDGPU from -mtriple=amdgcn ... -mcpu=<gfx> to
the folded subarch triple form (e.g. -mtriple=amdgpu9.00-amd-amdhsa), dropping
the redundant -mcpu.

[RISCV][P-ext] Fold packed insert-into-zero to zero-extend (#208006)
An insert_subvector of a 32-bit packed type (v4i8/v2i16) into a zero-filled
64-bit packed vector at index 0 is a zero-extend. Fold it so RV64 emits a
single zext.w instead of scalarizing into a byte-wise repack; RV32
concatenates with a zero half into the GPRPair.
[SPIR-V] Preserve offset alignment in pointer cast legalization (#209251)
Splitting a load/store into per-element accesses reused the original
alignment for every element, which could wrongly strengthen or discard
alignment
Compute each split access alignment via commonAlignment with its
DataLayout derived byte offset matching SPIRVLegalizerInfo.cpp
[SPIR-V] Remove dead typed pointer check in getArgSPIRVType (#209515)
Arg->getType() can never be a TypedPointerType since opaque pointers are
now the only pointer representation in LLVM IR
rpki-client: only output config files on successful run
While the suggested cronjob is 'rpki-client -v && bgpctl reload' and thus
only reloads bgpd if rpki-client completes successfully, the output logic
creates a config file that might still be loaded by an operator by hand.
If an error occurred in one of the subprocesses, only output ometrics (if
requested) and do not generate bgpd, bird, csv, json, and ccr.

lang/swift6: Unbreak build with clang 21
Clang 21 appears to have a regression in wchar.h handling when c++20
modules funcationality is enabled. (Swift compiler uses clang's
modules function under the hood.)
This is a workaround to avoid a compilation error by defining the
macro _WCHAR_H_CPLUSPLUS_98_CONFORMANCE_ to 1 before the compiler
reads the system wchar.h.

[CycleInfo] Remove GenericCycle::TopLevelCycle. NFC (#209677)
moveTopLevelCycleToNewParent maintains TopLevelCycle eagerly, rewriting
the whole re-parented subtree with depth_first. When discovery nests k
cycles one by one this is quadratic, and the df_iterator walk plus its
visited set dominate construction on deep nests (~78% of time on a
1500-deep nest).
Walk ParentCycle links in getTopLevelParentCycle instead and delete the
member. The walk is valid during construction too: parent links are
always current, and discovery queries blocks whose innermost cycle sits
at the top of the forest being merged, so the walk is short.

[libc] Remove #include <sys/whatever.h> (#209449)
and replace with granular includes of type/macro proxy headers -- where
those headers exist. I'm leaving the creation of new proxy headers for
another patch.
