[PATCH] D60793: [Evaluator] Walk initial elements when handling load through bitcast

[Jon Roelofs via Phabricator via llvm-commits]

jroelofs added a comment.

I have a miscompile that seems to stem from sharing the same logic between loads and stores.

In the store case, allowing `evaluateBitcastFromPtr` to narrow the operation to apply only to the struct's 0th element means we lose the writes to the other struct elements whenever constant folding is unable to fold an integer literal bitcast into a struct:
