A pointer to a memory block, live or dead.
This object can be allocated into interpreter stack frames. If pointing to a live block, it is a link in the chain of pointers pointing to the block.
In the simplest form, a Pointer has a Block* (the pointee) and both Base and Offset are 0, which means it will point to raw data.
The Base field is used to access metadata about the data. For primitive arrays, the Base is followed by an InitMap. In a variety of cases, the Base is preceded by an InlineDescriptor, which is used to track the initialization state, among other things.
The Offset field is used to access the actual data. In other words, the data the pointer decribes can be found at Pointee->rawData() + Pointer.Offset.
