[SelectionDAG] Fix null pointer dereference in resolveDanglingDebugInfo (#174341)
## Summary
Fix null pointer dereference in
`SelectionDAGBuilder::resolveDanglingDebugInfo`.
## Problem
`Val.getNode()->getIROrder()` is called before checking if
`Val.getNode()` is null, causing crashes when compiling code with debug
info that contains aggregate constants with nested empty structs.
## Solution
Move the `ValSDNodeOrder` declaration inside the `if (Val.getNode())`
block.
## Test Case
Reproduces with aggregate types containing nested empty structs:
```llvm
%3 = insertvalue { { i1, {} }, ptr, { { {} }, { {} } }, i64 }

[InstCombine] Shrink added constant using LHS known zeros (#174380)
Previously, `SimplifyDemandedUseBits` for `add` instructions only
used known zeros from the RHS to simplify the LHS. It failed to
handle the symmetric case where the LHS has known zeros and the
result does not demand the low bits.
This patch implements this missing optimization, allowing the RHS
constant to be shrunk when the LHS low bits are known zero and unused.

[compiler-rt] [ubsan] Fix missing include directory (#180341)
Fixes missing `-I` path that broke standalone builds in #179011. Matches
`include_directories()` in other compiler-rt libraries.

pkg-vulnerabilities: Remove duplicate inetutils entry
There was already an entry for CVE-2026-24061 and CVE-2026-24061 is not
fixed in 2.7 but will be fixed in a next release (or we should backport
them) via upstream commits fd702c02 and ccba9f74.
[libc++] Reduce the number of runs on the stop_token benchmarks (#179914)
Testing a bunch of sizes has relatively little value. This reduces the
number of benchmarks so we can run them on a regular basis.
Fixes #179697
