It removes templating for Elf_Rel[a] handling that we
introduced earlier and introduces a helper class instead.
It was briefly discussed in D87087, which showed,
why having templates is probably not ideal for the generalization
of dumpers code.

lowerShuffleWithPERMV allows us to use the ZMM variants for 128/256-bit variable shuffles on non-VLX AVX512 targets.
This is another step towards shuffle combining through between vector widths - we still end up with an annoying regression (combine_vpermilvar_vperm2f128_zero_8f32) but we're going in the right direction....
With `dynamic_tensor_from_elements` tensor values of dynamic size can be
created. The body of the operation essentially maps the index space to tensor
elements.
Declare SCF operations in the `scf` namespace to avoid name clash with the new

To enable the cost of constants, the helper function has been
reorganised:
- A struct has been introduced to hold SCEV operand information so
that we know the user of the operand, as well as the operand index.
The Worklist now uses instead instead of a bare SCEV.
- The costing of each SCEV, and collection of its operands, is now
performed in a helper function.

Decl::dump is primarily used for debugging to visualise the current state of a
declaration. Usually Decl::dump just displays the current state of the Decl and
doesn't actually change any of its state, however since commit
457226e02a the method actually started loading
additional declarations from the ExternalASTSource. This causes that calling
Decl::dump during a debugging session now actually does permanent changes to the
AST and will cause the debugged program run to deviate from the original run.
The change that caused this behaviour is the addition of
`hasConstexprDestructor` (which is called from the TextNodeDumper) which
performs a lookup into the current CXXRecordDecl to find the destructor. All
other similar methods just return their respective bit in the DefinitionData
(which obviously doesn't have such side effects).
This just changes the node printer to emit "unknown_constexpr" in case a
CXXRecordDecl is dumped that could potentially call into the ExternalASTSource
instead of the usually empty string/"constexpr". For CXXRecordDecls that can
safely be dumped the old behaviour is preserved

This change groups
* Rename: `ignoreParenBaseCasts` -> `IgnoreParenBaseCasts` for uniformity
* Rename: `IgnoreConversionOperator` -> `IgnoreConversionOperatorSingleStep` for uniformity
* Inline `IgnoreNoopCastsSingleStep` into a lambda inside `IgnoreNoopCasts`
* Refactor `IgnoreUnlessSpelledInSource` to make adequate use of `IgnoreExprNodes`
Differential Revision: https://reviews.llvm.org/D86880
Rationale:
This allows users to use `IgnoreExprNodes` and `Ignore*SingleStep` outside of
`clang/AST/Expr.cpp`.
Minor:
Rename `IgnoreImp...SingleStep` into `IgnoreImplicit...SingleStep`.

Vector to SCF conversion still had issues due to the interaction with the natural alignment derived by the LLVM data layout. One traditional workaround is to allocate aligned. However, this does not always work for vector sizes that are non-powers of 2.
This revision implements a more portable mechanism where the intermediate allocation is always a memref of elemental vector type. AllocOp is extended to use the natural LLVM DataLayout alignment for non-scalar types, when the alignment is not specified in the first place.
An integration test is added that exercises the transfer to scf.for + scalar lowering with a 5x5 transposition.

When using the always break after return type setting:

Before: _Atomic(uint64_t) * a;
After: _Atomic(uint64_t) *a;
This treats _Atomic the same as the the TypenameMacros and decltype. It
also allows some cleanup by removing checks whether the token before a
paren is kw_decltype and instead checking for TT_TypeDeclarationParen.
While touching this code also extend the decltype test cases to also check
for typeof() and _Atomic(T).

This adds a `AttributeMacros` configuration option that causes certain
identifiers to be parsed like a __attribute__((foo)) annotation.
This is motivated by our CHERI C/C++ fork which adds a __capability
qualifier for pointer/reference. Without this change clang-format parses
many type declarations as multiplications/bitwise-and instead.
I initially considered adding "__capability" as a new clang-format keyword,
but having a list of macros that should be treated as attributes is more
flexible since it can be used e.g. for static analyzer annotations or other language
extensions.
Example: std::vector<foo * __capability> -> std::vector<foo *__capability>
Depends on D86775 (to apply cleanly)

Modify FoldBranchToCommonDest to consider the cost of inserting

The threshold can be controlled via a new option:

When optimising for size, make the cost of i1 logical operations
