[mlir] Cleanup Operation.cpp (NFC) (#197712)
This PR cleans up the Operation.cpp based on clangd suggestions. It
removes unused headers, fixes incorrect comments, and improves
performance by applying std::move where appropriate.
[AArch64][GlobalISel] Fold buildvector of bitcast (#141553)
This adds a combine for buildvectors from bitcast values, sinking the
bitcast and generating a buildvector from the original scalar type.
```
%5:_(<4 x s8>) = G_BITCAST %16:_(s32)
%18:_(s8), %19:_(s8), %20:_(s8), %21:_(s8) = G_UNMERGE_VALUES %5:_(<4 x s8>)
%22:_(s8) = G_IMPLICIT_DEF
%23:_(<8 x s8>) = G_BUILD_VECTOR %18:_(s8), %19:_(s8), %20:_(s8), %21:_(s8), %22:_(s8), %22:_(s8), %22:_(s8), %22:_(s8)
=>
%undef:_(s32) = G_IMPLICIT_DEF
%bv:_(<2 x s32>) = G_BUILD_VECTOR %16:_(s32), %undef:_(s32)
%23:_(<8 x s8>) = G_BITCAST %bv:_(<2 x s32>)
```
It helps clean up some of the inefficiencies from widening scalar types.
usr.sbin/relayd: handle HTTP responses without bodies
RFC 9112 section 6.3 specifies that responses to HEAD requests, and
responses with 1xx, 204, or 304 status codes, are terminated by the
empty line after the header section regardless of Content-Length or
Transfer-Encoding. They cannot contain a message body or trailer
section.
Teach relayd to apply that framing rule before deciding whether a
response body is bounded. Otherwise relayd treats these responses as
unbounded, adds Connection: close, and can forward both the backend's
Connection: keep-alive and its own Connection: close.

Fixup"[llvm-ir2vec] Breaking up llvm-ir2vec lib implementation to clean up MIR deps from ir2vec python bindings (#194414)" (#198077)
llvm-ir2vec and LLVMMIREmbUtils was missing some deps which show up when
-DBUILD_SHARED_LIBS=ON. Fixed the Cmakelists.txt to reflect accurate
dependencies
sys/atomic.h: Avoid needless stack spillage with typeof_unqual.
Using typeof_unqual strips the volatile qualifier on the local
temporaries, so the compiler doesn't issue store/load cycles for
access to them.

Import devel/scnlib
scnlib is a modern C++ library for replacing scanf and std::istream.
This library attempts to move us ever so much closer to replacing
iostreams and C stdio altogether. It's faster than iostream, and
type-safe, unlike scanf. Think {fmt} or C++20 std::format, but in
the other direction.
