Reland "[llvm-profgen] Add support for ETM trace decoding" (#194465)
This relands commit e3bd61890e68303a33fdd33fbdd9abeda (#191584), which
was reverted in commit
ec9d7d18bdfe21c30c94c02f14f3613f7b69a17b (#194087) due to bot failures
on ppc64le and Windows.
This reland incorporates the following fixes:
1) Rename member variable InputFile to InputFilePath inside struct
InputFile to resolve MSVC shadow
conflicts.
2) Add arm-registered-target to ETM tests REQUIRES directive to prevent
failures on builders that do
not have the ARM target enabled.
[libc][test] Remove non-proxy header in sendmsg_recvmsg_test.cpp (#194467)
The header `include/llvm-libc-macros/linux/sys-socket-macros.h` should
be included via `hdr/sys_socket_macros.h` which proxies based on whether
LIBC_FULL_BUILD is enabled. Else we mix LLVM-libc internal headers and
system headers.
packages: Fix clang conditional
Various src.conf options can cause us to build something that ends up
in the clang package, but MK_TOOLCHAIN is not one of them; copy the
proper conditional from lib/Makefile to decide if we need to build
the package.
This fixes the build when LLVM/clang is entirely disabled.

[lldb] Unify python shebangs (#187257)
As per PEP-0394[1], there is no real concensus over what binary names
Python has, specifically 'python' could be Python 3, Python 2, or not
exist.
However, everyone has a python3 interpreter and the scripts are all
written for Python 3. Unify the shebangs so that the ~50% of shebangs
that use python now use python3.

[Offload][libsycl][clang-sycl-linker] Simplify SYCL Offload wrapping (#193876)
Replace the __sycl_tgt_bin_desc/__sycl_tgt_device_image-based fat binary
registration with a simpler OffloadBinary-native approach:
- __sycl_register_lib/__sycl_unregister_lib now take (BinaryStart, Size)
instead of a __sycl_tgt_bin_desc pointer; __sycl_unregister_lib only
needs BinaryStart since the runtime looks up the binary by its start
address.
- OffloadWrapper's SYCL wrapping is significantly simplified: the
__tgt_bin_desc/__tgt_device_image structs and the descriptor
construction code are replaced by a single embedded OffloadBinary blob
passed directly to the register/unregister entry points.
- clang-sycl-linker generates a single OffloadBinary, which contains
multiple images.
- ProgramAndKernelManager::registerFatBin parses the blob via
OffloadBinary::create, keying MDeviceImageManagers by BinaryStart to
eliminate the reparse on unregister.
- DeviceImageManager owns std::unique_ptr<OffloadBinary> instead of

[CIR] Eliminate SymbolTable::lookupSymbolIn hotspots (#193362)
mlir::SymbolTable::lookupSymbolIn is O(n) per lookup, so cumulative
symbol lookups during CIRGen are O(n^2) in the number of global symbols.
On template-heavy translation units this becomes a significant
compile-time hotspot.
Replace the SymbolTable lookup path with a per-CIRGenModule DenseMap
cache keyed by symbol name, giving O(1) lookups.
On a synthetic template-heavy stress test, end-to-end compile time on
`clang -fclangir -S -emit-llvm -O0` improves by ~11% on a 33K-LOC input
(5.86s -> 5.21s) and ~16% on a 67K-LOC input (16.09s -> 13.52s). The
super-linear growth of the win with input size confirms the O(n^2) ->
O(n) effect.
Similar to previous compile time fix, repro shape (scale records and
template instantiations into the hundreds/thousands to amplify):

libzpool: Set -Wno-error=typedef-redefinition for clang
In some versions of LLVM (at least 21), the <*intrin.h> headers contain
unguarded duplicate typedefs; this isn't permitted prior to C11, and
libzpool is built as C99. FreeBSD's LLVM backported LLVM PR #153820
to fix this, but other versions of LLVM (e.g., upstream, or on Linux)
don't have the patch, so this breaks the build.
Add -Wno-error=typedef-redefinition to downgrade this from an error
to a warning.

[VPlan] Pass TTI + CostKind to spillCost instead of CostCtx (NFC) (#194417)
Instead of passing CostContext, directly pass the needed TTI and
CostKind. This makes the function easier to re-use in other places,
without the need of constructing VPCostContext.

Makefile.inc1: Always use ${PKG_CMD}
Previously we had a mix of ${PKG_CMD} and bare 'pkg', which is
wrong, and breaks the build when 'pkg' isn't in the tools path,
e.g. when cross-building.

[NVPTX] Add reverseBranchCondition and CBranch inverted flag (#191889)
Add flag to `CBranch` instruction for inverted predicate branches (`@!p
bra`) and implement `reverseBranchCondition` to support branch condition
inversion.
This enables passes like branch folding to properly reverse branch
conditions, and is a prerequisite for SETP predicate inversion CSE.

[Sema] Enforce parameter match for ownership_returns attribute (#192339)
Previously parsing multiple ownership_returns attributes with different
arguments could lead to a crash. The documentation states that if
forward declarations have ownership_returns, they must have the same
arguments, and it may appear at most once per declaration.
This patch ensures that if multiple ownership_returns attributes are
present, their arguments (identifier and the optional index) must
exactly match. The diagonstic err_ownership_param_mismatch is introduced
for clarity.
Test cases for f15, C::f, and the newly added f22 were also updated to
match the requirement that all declarations of ownership_returns have
the same arguments, using the err_ownership_param_mismatch diagonstic.
