[PATCH] D50491: [DAGCombiner][AMDGPU][Mips] Fold bitcast with volatile loads if the resulting load is legal for the target.

I guess we could assume anyone using memory-mapped hardware will only do it with legal types, so reducing the number of operations for illegal types doesn't matter.  But please add a comment here (and to the related store transform) explaining that.
