class CachedSize

Defined at line 165 of file ../../third_party/protobuf/src/src/google/protobuf/message_lite.h

Allow easy change to regular int on platforms where the atomic might have a

perf impact.

CachedSize is like std::atomic

<int

> but with some important changes:

1) CachedSize uses Get / Set rather than load / store.

2) CachedSize always uses relaxed ordering.

3) CachedSize is assignable and copy-constructible.

4) CachedSize has a constexpr default constructor, and a constexpr

constructor that takes an int argument.

5) If the compiler supports the __atomic_load_n / __atomic_store_n builtins,

then CachedSize is trivially copyable.
