[clang][RISCV][Zicfilp] Force user to use `-mcf-branch-label-scheme=unlabeled` (#152122)
Expected Behavior:
When `-fcf-protection=branch|full` is specified, it's an error to omit
`-mcf-branch-label-scheme=unlabeled`.
Context:
When using forward-edge control flow integrity feature based on the
RISC-V Zicfilp extension, the `-mcf-branch-label-scheme` option selects
the encoding scheme used in the landing pad labels. The spec defines 2
schemes: `func-sig` and `unlabeled`, with the former specified as the
default. However the `func-sig` backend is still under active
development and won't land anytime soon; in the meanwhile, the
`unlabeled` scheme almost has complete support in the toolchain now.
Given that Clang currently accepts and defaults to
`-mcf-branch-label-scheme=func-sig` but doesn't work correctly, we want

[AArch64][TG] Migrate AArch64 backend from !cond to !switch(NFC) (#200949)

[mlir][IR] Require token producer and consumer traits
Add marker traits for operations that intentionally produce or consume the
builtin token type. The verifier now rejects token results without
TokenProducerTrait, token operands without TokenConsumerTrait, token entry
block arguments whose parent op does not produce tokens, and token block
arguments outside entry blocks.
Extend the Test dialect token ops to cover valid opt-in cases and each
verifier rejection path.

[VPlan] Replace VPTypeAnalysis with VPValue::getScalarType. (NFC) (#200256)
Now that all VPValues have their scalar type set at construction,
replace calls to VPTypeAnalysis::inferScalarType with direct calls to
VPValue::getScalarType, and remove the no-longer-needed VPTypeAnalysis
members from VPCostContext and VPTransformState. Also remove the
getScalarTypeOrInfer fallback helper.
Depends on https://github.com/llvm/llvm-project/pull/200255

[VPlan] Fix assertion when VPReductionPHIRecipe is simplified (#201023)
When replacing an invariant store of a reduction, we assert that the
stored value is the backedge value. However in some cases the
VPReductionPHIRecipe may be simplified away completely, so account for
this.
Fixes #201020
Fixes #200742
[compiler-rt][sanitizer_common] Generalize CheckNoDeepBind as OnDlOpen (#200748)
Rename the dlopen pre-check hook to OnDlOpen so platform-specific dlopen
handling can be extended beyond the RTLD_DEEPBIND guard on Linux.
Windows and macOS keep no-op implementations. All dlopen interceptors
call the shared hook.

This falls back to the key which isn't going to be translated
since it's likely a technical term or keyword.
Also translate the $subvalue which appears to have been missed
before.

[VPlan] Don't print interleave group insert position. (#200023)
This patch updates interleave group printing to drop the insert
position. It does not add any information (the position of the
interleave group is determined by the position in VPlan), and for stores
we currently were printing <badref> anyways (trying to print a value
with void type).

[VPlan] Propagate interleave-group metadata to narrowed wide load/store. (#199356)
VPInterleaveRecipe now carries the common metadata valid for all members
and as such hold for any member. Propagate it to narrowed load and
stores.
