[X86] lowerShuffleAsDecomposedShuffleMerge - prefer BLEND(X,SHUFFLE(Y)) over UNPCKL(SHUFFLE(X), SHUFFLE(Y)) (#208503)
If blends are cheap and at least one input is a noop - perform a
permute+blend
remove ParserConversionAction, add paramter to ParseStringLiteralExpression instead, add conversion to SystemCharset then back to UTF8 to handle escape sequences in system encoding
[VPlan] Fold Plan variable in single user in verifyLastActivLane (NFC) (#208505)
In release builds, the variable is now unused. Sink and inline into
single user to silence warning.
[libc] Remove CUDA Toolkit dependency for NVPTX build (#208497)
This was problematic because these CMake headers were never intended to
be used from a GPU target. We had to hack around this to suppress
threads, but all this is used for is getting the default CUDA path, so
just do this directly.
[SLP] Support FAdd/FSub as interchangeable instructions
fadd(x, c) and fsub(x, c) are interchangeable via fadd(x, -c), so treat
them like the existing Add/Sub/Mul/Shl/AShr/And/Or/Xor interchange in
BinOpSameOpcodeHelper. This lets a mixed fadd/fsub bundle vectorize as
a single op instead of needing an alt-shuffle/split node.
Restrict the interchange to a constant RHS. A constant LHS (e.g.
"0.0 - x") cannot be moved to the other opcode without also swapping
the variable operand, which would misalign it against lanes that keep
their native opcode and produce a node too expensive to vectorize.

Potentially-incompatible changes
--------------------------------
* sshd(8): configuration dump mode ("sshd -G") now writes directives
in mixed case (e.g. "PubkeyAuthentication") whereas previously it
emitted only lower-case names.
* ssh(1), sshd(8): make the transport protocol stricter by
disconnecting if the peer sends non-KEX messages during a post-
authentication key re-exchange. Previously a malicious peer could
continue sending non-key exchange messages without penalty. These
would be buffered, causing memory to be wasted up until the

Fix receive of split large blocks with a short trailing chunk
A dataset with a large recordsize can store a single-block file whose
block size is not a power of two. When such a block is sent without
large blocks (no -L), the sender splits it into SPA_OLD_MAXBLOCKSIZE
(128K) chunks, and the final chunk is smaller than the block size.
flush_write_batch_impl() already handles any WRITE record whose size
differs from the object's block size by doing a normal dmu_write(), but
it first asserted the record was always larger than the block size. The
shorter trailing chunk violates that assertion, so receiving such a
stream panicked the receive_writer thread on debug builds; production
builds took the correct dmu_write() path and were unaffected.
Drop the assertion and describe both size-mismatch cases in the comment;
the dmu_write() path already handles a record smaller than the block
size. Add an rsend test that sends such a block without -L (initial and
incremental, plain and compressed) and verifies the received file
matches.

[AMDGPU][test] Split slow lit tests for better parallel lit throughput (NFC)
Split the slowest AMDGPU CodeGen tests into independent lit units so
llvm-lit can distribute work across available host cores.
[libc++] Remove benchmark::DoNotOptimize from custom predicates in benchmarks (#208412)
The point of the custom predicates is to defeat any detection of special
predicates within the library. There isn't much point in adding
`benchmark::DoNotOptimize` on top of that. It can actually hurt, since
it may hide performance changes due to how much/which information we
provide to the compiler.
