[AMDGPU] Add dot product patterns with saturating add (clamp) (#187945)
Add pattern matching for dot product operations combined with saturating
add intrinsics (llvm.uadd.sat / llvm.sadd.sat). This enables the
compiler to generate dot instructions with the clamp modifier instead of
separate dot + saturating add instructions.
Fixes #182095
## Changes
- Added UDot2SatPat and SDot2SatPat TableGen pattern classes that match
uaddsat/saddsat with dot2 computations
- Added performSatAddCombine DAG combiner function to handle
ISD::UADDSAT and ISD::SADDSAT nodes
- Added test file idot2-sat.ll
## Example

Introduce and use dtls12_handshake_msg.
Add struct dtls12_handshake_msg and various related functions, which
allow for the construction of DTLS handshake messages and associated
fragments.
Use this on the DTLS write path for sending handshake message fragments.
This means that we no longer modify the init buffer, which also fixes a
bug where the message callback is called with a corrupted handshake
message when multiple fragments have been sent.
We also now correctly track fragment offsets when sending a handshake
message that results in multiple calls to dtls1_do_write_handshake_message().
This is the first step towards further untangling of the write path in
the legacy TLS stack.

Revert "[clang][NFC] Mark CWG717 as implemented and add a test (#197732)" (#198074)
As reported in #197930, these new tests fail on the
`arm64-apple-darwin-unknown` target. There's not a consensus yet on how
to fix the breakage, so revert it until we can decide.
kernel: Use lockowned() instead of (lockstatus(&lock, curthread) != 0).
It is sufficient and more lightweight.
Most of these lockstatus() were added by me.
