[clang][Lex] Unique ModuleMacros with a UniquingSet (NFC) (#223270)
This patch migrates ModuleMacros in Preprocessor from llvm::FoldingSet
to llvm::UniquingSet.
ModuleMacro keys on a pair of Module * and const IdentifierInfo *.
Switching to UniquingSet allows us to look up macros with a typed key,
eliminating FoldingSetNodeID serialization at lookup sites and removing
ModuleMacro::Profile.

[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.
