Looking at the AST-level `getReadImpl` doesn't always correspond to what accessor SILGen prefers to use, due to resilience, ABI rules, and other concerns. In findStorageReferenceExprForMoveOnly, when determining whether a storage reference is borrowable, use the same logic as SILGenLValue actually uses to determine what storage or accessor access strategy to use.
