Philip Reames 89e92d21b4 [PR29121] Don't fold if it would produce atomic vector loads or stores ...

The instcombine code which folds loads and stores into their use types can trip up if the use is a bitcast to a type which we can't directly load or store in the IR. In principle, such types shouldn't exist, but in practice they do today. This is a workaround to avoid a bug while we work towards the long term goal.
