Nicola Zaghen 97572775d2 Reland [DataLayout] Fix occurrences that size and range of pointers are assumed to be the same. 
GEP index size can be specified in the DataLayout, introduced in D42123. However, there were still places
in which getIndexSizeInBits was used interchangeably with getPointerSizeInBits. This notably caused issues
with Instcombine's visitPtrToInt; but the unit tests was incorrect, so this remained undiscovered.

This fixes the buildbot failures.

Nicola Zaghen f798eb21ec Temporarily Revert "[DataLayout] Fix occurrences that size and range of pointers are assumed to be the same." 
This reverts commit 5f6208778f.

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