This patch fixes an invalid TypeSize->uint64_t implicit conversion in
FoldReinterpretLoadFromConst. We now check to see if the offset is

> the known minimum size of the constant. In addition, I have added
> =================================================================

support for scalable vector splats in ReadDataFromGlobal, since
we can support load-store forwarding when we know the offset is safe.
