[PATCH] D15845: [ADT] Switch from a hacky use of PointerIntPair and poorly chosen arbitrary integers cast to Instruction pointers to a sum type over Instruction * and a PointerEmbeddedInt.

[Chandler Carruth via llvm-commits]

chandlerc created this revision.
chandlerc added a subscriber: llvm-commits.
chandlerc added a dependency: D15843: [ADT] Add a sum type abstraction for pointer-like types..

This is a good example of how PointerSumType and PointerEmbeddedInt can be used
to create a more clean sum type abstraction.

No functionality changed.

Depends on D15843.
Depneds on D15844.
