Fix a miscompile introduced by 99203f2.

getPointersDiff would previously round down the difference between two
pointers to a multiple of the element size of the pointee, which could
result in a pointer value being decreased a little.

Alexey Bataev has graciously agreed to add a testcase for this;
submitting the bugfix now to unblock.
