Temporarily Revert "[DataLayout] Fix occurrences that size and range of pointers are assumed to be the same."

This reverts commit 5f6208778ff92567c57d7c1e2e740c284d7e69a5.

This caused failures in Transforms/PhaseOrdering/scev-custom-dl.ll
const: Assertion `getBitWidth() == CR.getBitWidth() && "ConstantRange types don't agree!"' failed.
