[SelectionDAG] Emit `AssertZext` for function argument range attributes

[SelectionDAG] Drop unnecessary lower bound check in lowerRangeToAssertZExt

[DAGCombiner] Fix abs(add) to abdu miscompile in foldABSToABD

[mlir][IR] Add builtin `TokenTypeInterface`

type instead of type interface

[SPIR-V] Fix inttoptr type deduction with ptr.annotation (#189219)

Opaque pointer inttoptr was recording ptr as a pointee type, so
OpConvertUToPtr was emitted as pointer-to-pointer and then bitcasted
back. Please see an example below.

LLVM IR:
```
%p = inttoptr i64 %x to ptr addrspace(1)
%a = call ptr addrspace(1) @llvm.ptr.annotation(... %p ...)
call spir_func void @prefetch(ptr addrspace(1) %a, ...)
```

SPIR-V (before the change):
```
%p2 = OpConvertUToPtr %_ptr_CrossWorkgroup__ptr_CrossWorkgroup_uchar %x
%p1 = OpBitcast %_ptr_CrossWorkgroup_uchar %p2
OpFunctionCall ... %p1 ...
```

[DAG][GISel] Rename CTTZ_ZERO_UNDEF/CTLZ_ZERO_UNDEF/CTTZ_ELTS_ZERO_UNDEF -> CTTZ_ZERO_POISON/CTLZ_ZERO_POISON/CTTZ_ELTS_ZERO_POISON (#196732)

DAG/GISel are ambiguous about whether zero-input results in
UNDEF/POISON, unlike the rest of LLVM which makes it clear its POISON.

I've tried to clean this up once and for all by ensuring
SelectionDAG::canCreateUndefOrPoison does a includesPoison(Kind) check,
renaming the opcodes (including the VP variants) and updating as many
comments/tests as possible (I may still have missed some...).

[AArch64] Report accurate sizes for MOVaddr and MOVimm pseudos

[NFC][AArch64] Extract MOVaddr* expansion model into common header

This makes the expansion logic reusable by getInstSizeInBytes in a
follow-up patch.

[clang-tidy] Remove hicpp module [1/4] (#194516)

This is part one of removing the `hicpp-*` checks.

RFC:
https://discourse.llvm.org/t/rfc-regarding-the-current-status-of-hicpp-checks/89883

[cmake] use target names instead of legacy variables (#185463)

Use the [name of the imported
targets](https://cmake.org/cmake/help/latest/module/CheckSymbolExists.html)
when testing the libraries during cmake configuration. This removes the
need to also set `CMAKE_REQUIRED_INCLUDES` and
`CMAKE_REQUIRED_DEFINITIONS` and reflects more modern CMake usage where
targets are preferred over variables.

This is already the case when checking libcurl in the same file.

[Clang] Transform lambda's constraints when instantiating parameter mapping (#195995)

This way we can remove a few workarounds of lambda expressions where
outer template arguments of concepts have to be preserved through
ImplicitConceptSpecializationDecls.

Fixes #193944

[ADT] Remove xxHash64 ArrayRef/StringRef overloads. NFC (#196781)

xxHash64 is a legacy, pre-XXH3 hash whose only non-test caller in the
monorepo is llvm::getKCFITypeID. #196774 accidentally exposed the API.

[libc] Add barebones dl_iterate_phdr implementation (#194196)

Add a basic dl_iterate_phdr implementation so that we can get libunwind
building. This implementation is bare and not fully compliant with the
man page for fully static binaries (which are all that we support
currently with the lack of a dynamic linker) due to the lack of TLS
info, but that can be added at a future date if it is needed, as it is
not needed by libunwind.

Add some very basic smoke tests.
