[PATCH] D32059: Make AssumptionCache's interface return a range of Values

[Yoav Ben-Shalom via Phabricator via llvm-commits]

yabash created this revision.
Herald added a subscriber: mzolotukhin.

Instead of returning a range of WeakVHs,
forcing every user of the interface to check the WeakVH before using it,
return a range which filters out the null WeakVHs and dereferences it.

This is a fix for a FIXME by @djasper.
