Return exclusive upper bound on object size.
The theoretical maximum object size is defined as the maximum positive isize
value.
This ensures that the offset
semantics remain well-defined by allowing it to correctly
index every address within an object along with one byte past the end, along with allowing
isize
to store the difference between any two pointers into an object.
The upper bound on 64-bit currently needs to be lower because LLVM uses a 64-bit integer to represent object size in bits. It would need to be 1 << 61 to account for this, but is currently conservatively bounded to 1 << 47 as that is enough to cover the current usable address space on 64-bit ARMv8 and x86_64.
