In the previous patch (#127753), the suggested approach was to enhance getTgtMemIntrinsic(). However, I realized that getTgtMemIntrinsic() is already used for specific purposes (e.g., EarlyCSE), so in this patch, I'm still adding a new TTI hook instead.

The main difference is that I'm no longer renaming `InterestingMemoryOperand` to `MemoryRefInfo`, as I did in the previous patch. This avoids the need to modify other targets like AMDGPU, which makes the change more contained and less intrusive.
