Since I’m not using our existing `Value`, I introduced a universal buffer for
built-in types (including strings).
```cpp
class BuiltinValueBuffer : public ValueBuffer {
public:
std::vector<uint8_t> raw;
BuiltinValueBuffer(QualType _Ty) : ValueBuffer(K_Builtin) {
Ty = _Ty;
}
template <typename T>
T as() const {
T v{};
// Ensure the buffer is large enough for the requested type.
memcpy(&v, raw.data(), sizeof(T));
return v;
}
static bool classof(const ValueBuffer *B) {
return B->isBuiltin();
}
};
```
I use `ValueBuffer` to read memory directly into a buffer sized for the type,
and at print time we cast the raw data back to the correct type.
If we use a `Value`-kind structure, we need to read memory, cast it, and set
the value at read time.
