[SandboxVec][BottomUpVec] Disable crossing BBs (#124039)
c7053ac 
Crossing BBs is not currently supported by the structures of the
vectorizer. This patch fixes instances where this was happening,
including:
- a walk of use-def operands that updates the UnscheduledSuccs counter,
- the dead instruction removal is now done per BB,
- the scheduler, which will reject bundles that cross BBs.

Reapply "[llvm-objcopy][ELF] Add an option to remove notes (#118739)"
1077280 
This fixes "unused-local-typedef" warnings in 9324e6a.

This adds an option `--remove-note=[name/]type` to selectively delete
notes in ELF files, where `type` is the numeric value of the note type
and `name` is the name of the originator. The name can be omitted, in
which case all notes of the specified type will be removed. For now,
only `SHT_NOTE` sections that are not associated with segments are
handled. The implementation can be extended later as needed.

[IA] Generalize the support for power-of-two (de)interleave intrinsics (
bc74a1e 
#123863)

Previously, AArch64 used pattern matching to support
llvm.vector.(de)interleave of 2 and 4; RISC-V only supported
(de)interleave of 2.

This patch consolidates the logics in these two targets by factoring out
the common factor calculations into the InterleaveAccess Pass.

Reland: [clang] unified CWG2398 and P0522 changes; finishes implement…
28ad897 
…ation of P3310 (#124137)

This patch relands the following PRs:
* #111711
* #107350
* #111457

All of these patches were reverted due to an issue reported in
#111711 (comment),
due to interdependencies.

[clang] Finish implementation of P0522

This finishes the clang implementation of P0522, getting rid
of the fallback to the old, pre-P0522 rules.

Before this patch, when partial ordering template template parameters,
we would perform, in order:
* If the old rules would match, we would accept it. Otherwise, don't
  generate diagnostics yet.
* If the new rules would match, just accept it. Otherwise, don't
  generate any diagnostics yet again.
* Apply the old rules again, this time with diagnostics.

This situation was far from ideal, as we would sometimes:
* Accept some things we shouldn't.
* Reject some things we shouldn't.
* Only diagnose rejection in terms of the old rules.

With this patch, we apply the P0522 rules throughout.

This needed to extend template argument deduction in order
to accept the historial rule for TTP matching pack parameter to non-pack
arguments.
This change also makes us accept some combinations of historical and P0522
allowances we wouldn't before.

It also fixes a bunch of bugs that were documented in the test suite,
which I am not sure there are issues already created for them.

This causes a lot of changes to the way these failures are diagnosed,
with related test suite churn.

The problem here is that the old rules were very simple and
non-recursive, making it easy to provide customized diagnostics,
and to keep them consistent with each other.

The new rules are a lot more complex and rely on template argument
deduction, substitutions, and they are recursive.

The approach taken here is to mostly rely on existing diagnostics,
and create a new instantiation context that keeps track of this context.

So for example when a substitution failure occurs, we use the error
produced there unmodified, and just attach notes to it explaining
that it occurred in the context of partial ordering this template
argument against that template parameter.

This diverges from the old diagnostics, which would lead with an
error pointing to the template argument, explain the problem
in subsequent notes, and produce a final note pointing to the parameter.

[clang] CWG2398: improve overload resolution backwards compat

With this change, we discriminate if the primary template and which partial
specializations would have participated in overload resolution prior to
P0522 changes.

We collect those in an initial set. If this set is not empty, or the
primary template would have matched, we proceed with this set as the
candidates for overload resolution.

Otherwise, we build a new overload set with everything else, and proceed
as usual.

[clang] Implement TTP 'reversed' pack matching for deduced function template calls.

Clang previously missed implementing P0522 pack matching
for deduced function template calls.

[lld-macho] Implement symbol string deduplication (#123874)
c676104 
The symbol string table does not have deduplication. 
Here we add code to deduplicate the symbol string table. 
This has a rather large size impact (20-30%) on unstripped binaries
(typically debug binaries) but no size impact on stripped
binaries(typically release binaries).

We enable deduplication by default and add a flag to disable it
(`-no-deduplicate-symbol-strings`).

[MachineSink] Extend loop sinking capability (#117247)
acb7859 
The current MIR cycle sinking capabilities are rather limited. It only
support sinking copies into a single successor block while obeying
limits.

This opt-in feature adds a more aggressive option, that is not limited
to the above concerns. The feature will try to "sink" by duplicating any
top-level preheader instruction (that we are sure is safe to sink) into
any user block, then does some dead code cleanup. In particular, this is
useful for high RP situations when loop bodies have control flow.
