[RISCV][MC] Add experimental Smidctrl, Ssidctrl, Smnip, and Ssnip support (#218108)
Add experimental MC support for Smidctrl, Ssidctrl, Smnip, and Ssnip
extensions.
This completes MC support for the ACLIC v0.20 extensions.
security/vuxml: Document gitea < 1.27.3 vulnerabilities
Gitea 1.27.3 fixes 26 security issues, hardens issue searching
that an unfiltered query no longer enumerates every public
repository into the indexer filter and removes unsafe code
from the internal private endpoints.

[lldb] Test undefined return addresses in signal frames (#223046)
Signal-frame CFI can explicitly mark its return-address register
undefined to represent a terminal synthetic context. This is useful for
contexts such as newly created FreeBSD kernel threads that do not have
an interrupted caller.
Verify that LLDB keeps the signal frame in the backtrace and terminates
the unwind without creating a caller.

[VPlan] Set the containing plan when creating blocks (NFC). (#223269)
Now that we funnel all VP block creation through VPlan helpers, make
sure the Plan field is set for each block. This means we can remove the
CFG walk to find a Plan's entry.
Also drop an assertion in VPSlotTracker::getOrCreateName: a block now
knows its plan as soon as it is created.
This has a very small positive compile-time impact.
[VPlan] Fold shifts by zero. (#223276)
Add trivial folds of shifts by zero. This allows us to match IR SCEV
behavior (which looks through trivial shifts), w/o explicitly handling
those in getSCEVExprForVPValue.
[VPlan] Add tests for narrowing users of a widened induction (NFC). (#223277)
Add additional narrowing tests for wide IV including pointer inductions
and FP inductions.
sysutils/ngbuddy: Update 1.0 => 1.1
This update also corrects rc.d service order
reported by feld@ in PR 298188.
While here, update maintainer address.

[AArch64] Make ImmInsnModel operands optional. NFC (#223280)
This helps make sure we do not use them incorrectly, and should allow
them to
be checked for values in the future.
[SSAF][SourceEdit] Wire in 'clang-ssaf-src-edit-merge' and add multi-TU tests (#220372)
With 'clang-ssaf-src-edit-merge', we can test source edits over multiple
translation units: their Replacements are merged before apply. This
covers both clean merges and conflicts.
[SSAF][SourceTransformation] Add transformation for new[] and malloc
For a PointerFlowPair, if RHS is an array-new or malloc call and LHS
has bounded type, transform RHS to the bounded-producing alternative
to new[]/malloc.

[AMDGPU] Fix s_buffer_load crash for illegal result types (#215483)
i1, i4, v2i1, v3i16, v6i8, and i128 had no SBUFFER_LOAD selection
pattern and crashed
Load a legal i32/vNi32 carrier instead and narrow/bitcast down to the
requested type
[Clang][MinGW] Link default-manifest.o if exists (#223084)
Some MinGW distributions provide a pre-compiled manifest xml to disable
the UAC escalation dialog.
Link automatically the manifest only if it exists when linking an
executable.
Do the same as Cygwin (#220875) and align with GCC.
[VPlan] Don't create no-op casts in truncateToMinimalBitwidths. (#223271)
No-op casts get folded to the input operand, which caused applyFlags to
crash if that was not a cast. Fix by avoiding creating such trivial
casts in the first place.
