[SLP] Fix reduction cost crash for reduced values replaced by extractelement
A reduced value may be replaced by an extractelement while vectorizing a
previous subvector, so it is no longer a key in ReducedValsToOps.
Look through replaced values to the reduction operation among their users.

[AMDGPU][NFC] Templatise and roundtrip gfx13_asm_vop3_dpp16.s
Again, this is based on the templatised version of
gfx12_asm_vop3_dpp16.s with the GFX13-specific changes re-applied
on top of it.
gfx13_dasm_vop3_dpp16.txt was never upstreamed, so no changes for
the disassembler side.
[libcxx] Make std::pair pretty-printer ABI-independent (#201768)
std::pair is printed explicitly instead of relying on GDB's default
struct formatting to keep output stable across ABI configurations.
With _LIBCPP_DEPRECATED_ABI_DISABLE_PAIR_TRIVIAL_COPY_CTOR (default on
some platforms, e.g. FreeBSD), std::pair gains an empty
__non_trivially_copyable_base base class. GDB would otherwise render
this as <...__non_trivially_copyable_base<...>> = {<No data fields>},
which makes output ABI-dependent.
Only first and second are meaningful, so print them directly.
Fix __transform_primary in FreeBSD
FreeBSD's strxfrm() encodes collation weights one level at a time,
separating the primary, secondary, and tertiary with '.' bytes. Since
primary equivalence only depends on the primary collation weight, ignore
everything after the first separator when constructing the transformed
key.
This patch the intended behavior of primary equivalence and avoids
relying on glibc's fixed-size collation-key representation.
[libc] Implement basename and dirname in libgen.h (#204554)
Added the POSIX standard functions basename and dirname under a new
libgen.h header. The implementations modify the input path in-place
using cpp::string_view to determine boundaries safely.
Added find_last_not_of to cpp::string_view to support trailing slash
removal.
Implemented:
* libc/include/libgen.yaml, libgen.h.def: Public API definitions.
* libc/src/libgen/basename.cpp, dirname.cpp: Generic implementations.
* libc/test/src/libgen/: Unit and hermetic tests.
Registered the new entrypoints for all active Linux targets (x86_64,
aarch64, arm, riscv) and added docgen configuration.
Assisted-by: Automated tooling, human reviewed.
[clang] Avoid premature Twine .str() materialization (#204830)
Several call sites pass `expr.str()` to parameters of type `const
llvm::Twine &`, forcing a throwaway heap std::string that is immediately
rewrapped into a Twine. Drop the `.str()` and let Twine accept the
StringRef/concatenation directly.

AMDGPU/GlobalISel: Remove -new-reg-bank-select option
AMDGPU's -global-isel pipeline that uses AMDGPURegBankSelect and
AMDGPURegBankLegalize, previously -global-isel -new-reg-bank-select,
is now the default -global-isel pipeline.
Remove -new-reg-bank-select option from the compiler.
Remove -new-reg-bank-select from all llvm regression tests.
Edit a couple comments to reference RegBankLegalize instead of
-new-reg-bank-select.
[llvm][Target] Avoid premature Twine .str() materialization (#204836)
Call sites in the AMDGPU and SPIRV parsers and the SystemZ AsmPrinter /
InstrInfo pass `expr.str()` (or `.str().c_str()`) to parameters of type
`const llvm::Twine &`, forcing a throwaway heap std::string that is
immediately rewrapped into a Twine. Drop the materialization and let
Twine accept the concatenation directly.

This patch enables the fexec-charset option to control the execution charset of string literals. It sets the default internal charset, system charset, and execution charset for z/OS and UTF-8 for all other platforms.
