[PATCH] D48599: SCEVExpander::expandAddRecExprLiterally(): check before casting as Instruction

[Max Kazantsev via Phabricator via llvm-commits]

mkazantsev added a comment.

Frankly, I don't understand why we want it to be an instruction at all. Can these methods (i.e. `hoistIVInc` and `isNormalAddRecExprPHI`) be taught to work with values? For example, if it is not an instruction then we just consider it already hoisted.
