[clang][bytecode] Fix dummy handling for p2280r4 (#124396)

This makes some other problems show up like the fact that we didn't
suppress diagnostics during __builtin_constant_p evaluation.

[AST] Migrate away from PointerUnion::dyn_cast (NFC) (#124228)

[AST] Migrate away from PointerUnion::dyn_cast (NFC) (#124228)

Note that PointerUnion::dyn_cast has been soft deprecated in
PointerUnion.h:

// FIXME: Replace the uses of is(), get() and dyn_cast() with
// isa<T>, cast<T> and the llvm::dyn_cast<T>

Literal migration would result in dyn_cast_if_present (see the
definition of PointerUnion::dyn_cast), but this patch uses dyn_cast
because we expect Source to be nonnull.

[AST] Remove unused includes (NFC) (#116549)

Identified with misc-include-cleaner.

[clang][bytecode] Fix Pointer::toAPValue() for multidimensional arrays (#114400)

When we see an array root, that pointer might yet again be an array
element, so check for that.

[clang][bytecode] Change isArrayElement() for narrowed composite arrays (#111110)

Make isArrayElement() return true here, so we can know that such a
pointer is in fact an array element and handle i

[clang][bytecode] Change isArrayElement() for narrowed composite arrays (#111110)

Make isArrayElement() return true here, so we can know that such a
pointer is in fact an array element and handle it properly in
toAPValue().

[clang][bytecode] Start implementing fixed point types (#110216)

Add the primitive type and implement to-bool casts.

[clang][bytecode] Add a source location to destructor calls (#110121)

The added test case is still diagnosed differently, but I'm not sure
which version is better.

[clang][bytecode] Fix diagnosing std::construct_at with wrong type (#109828)

We can't make the assumption that types are always fine in std
functions.

[clang][bytecode][NFC] Get rid of const_casts in Move fns (#105698)

[clang] Rename all AST/Interp stuff to AST/ByteCode (#104552)

"Interp" clashes with the clang interpreter and people often confuse
this.
