[SDPatternMatch][NFC] Use empty SDNodeFlags instead of std::optional (#178483)
I think we can avoid using std::optional for SDNodeFlags in
UnaryOpc_match.

[AMDGPU] Introduce V_READANYLANE_B32
This is non-convergent pseudo suitable for uniform inputs.
The MachineInstr::NoConvergent attribute allows hoisting
which is otherwise prohibited for a convergent instruction.
[Clang] Fix coro_await_elidable breaking with parenthesized expressions
The applySafeElideContext function used IgnoreImplicit() to find the
underlying CallExpr, but this didn't strip ParenExpr nodes. When code
like `co_await (fn(leaf()))` was parsed, the operand was wrapped in a
ParenExpr, causing HALO (Heap Allocation eLision Optimization) to fail.
This fix chains IgnoreImplicit()->IgnoreParens()->IgnoreImplicit() to
handle both orderings of implicit nodes and parentheses in the AST.
Fixes the issue where adding parentheses around co_await's argument
would prevent heap elision for coro_await_elidable coroutines, which
is particularly problematic since parentheses are often required in
real-world code due to co_await's tight binding with operators.
textproc/libxml2: bump PORTREVISION to force rebuild
FreeBSD-ports-latest - for FreeBSD 15 - currently carries packages
that have the libxml2-core package as a dependency (and the
libxml2-core).
Bump PORTREVISION to force the package builder to resynch onto ports
where there is no libxml2-core package, to reduce confusion.
(2026Q1 is unaffected, it did not have this change.)
[mlir][tosa] Fix pad op verifier when padding is dynamic (#177622)
When padding is dynamic the verifier should not return failure, it
shouldn't try to check the pad values.
[DAG] SDPatternMatch - allow m_BinOp / m_c_BinOp to take an optional SDNodeFlags required for matching (#178435)
BinaryOpc_match is already wired up for this - but allow us to use
m_BinOp/m_c_BinOp with the required flags directly
Updated the foldShiftToAvg folds to make use of this
[InstCombine] Add combines for unsigned comparison of absolute value to constant (#176148)
This patch implements the following two peephole optimisations:
1. ``` abs(X) u> K --> K >= 0 ? `X + K u> 2 * K` : `false` ```;
2. If `abs(INT_MIN)` is `poison`, ```abs(X) u< K --> K >= 1 ? `X + (K -
1) u<= 2 * (K - 1)` : K != 0```.

security/xmlsec1: update to v1.3.9
This unbreaks libxml 2.15, where some pointer types went "const",
and the prior FreeBSD ports version of xmlsec1 wanted to error out
instead of seeing warnings (-Werror) and broke.

PR: 291316
(This builds with extant libxml2.14 and 2.15, so let's just commit this.)
(cherry picked from commit f09a210a25c877e8f82a8cde9aff64eb5cd958fc)
Improve resiliency in the tests.
Clean up changes. Reduce some retries.
Encapsulate one test in a class to avoid excessive reconfigurations and restarts.
