Cleaning up _all_ the scopes is a little too much. Only clean up until
the point here we started the scope relevant for the break/continue
statement.

We don't need the value in this case, since we're discarding it anyway.
Allow continuing the interpretation but note the side effect.

This requires adding a new opcode for PointerToBoolean casts, since we

[clang][bytecode] Fix the handling of address of a vector ( #106558 )
...
The PR https://github.com/llvm/llvm-project/pull/105996 broke taking the
address of a vector:
**compound-literal.c**
```C
typedef int v4i32 __attribute((vector_size(16)));
v4i32 *y = &(v4i32){1,2,3,4};
```
That because the current interpreter handle vector unary operator as a
fallback when the generic code path fail. but the new interpreter was
not. we need to handle `UO_AddrOf` in
`Compiler<Emitter>::VisitVectorUnaryOperator`.

...
Implement constexpr vector unary operators +, -, ~ and ! .
- Follow the current constant interpreter. All of our boolean operations
on vector types should be '-1' for the 'truth' type.
- Move the following functions from `Sema` to `ASTContext`, because we
used it in new interpreter.
```C++
QualType GetSignedVectorType(QualType V);
QualType GetSignedSizelessVectorType(QualType V);
```

[clang][bytecode] Support ObjC blocks ( #104551 )

I started out by adding a new pointer type for blocks, and I was fully
prepared to compile their AST to bytecode and later call them.
... then I found out that the current interpreter doesn't support
calling blocks at all. So we reuse `Function` to support sources other
than `FunctionDecl`s and classify `BlockPointerType` as `PT_FnPtr`.
