PtrInner
carries all invariants which are not controlled by type parameters. SincePtrInner
does not promise to uphold aliasing, alignment, or validity, we can move some utility methods toPtrInner
which previously were responsible for maintaining invariants orthogonal to their purpose.Makes progress on #1892 (still needs to be fixed on v0.8.x) Closes #1890
