<summary>Changes</summary>
Currently, a "null value" in LLVM means a zero value. We are moving toward
changing the semantics of `ConstantPointerNull` to represent a semantic null
pointer instead of a zero-valued pointer. As a result, the meaning of "null
value" will also change in the future.
This PR is a first step toward renaming the two widely used "null value"
interfaces to "zero value". Semantic "null value" interfaces will be added back
later together with the semantic changes to `ConstantPointerNull`.
