  [Matrix] Use shape info for StoreInst directly. (#142664)

ShapeInfo for the store operand may be dropped, e.g. because the operand
got folded by transpose optimizations to another instruction w/o shape
info. This was exposed by the assertion added in
https://github.com/llvm/llvm-project/pull/142416.

This updates VisitStore to use the shape-info directly from the
instruction, which is in line with the other Visit* functions and
ensures that we won't lose shape info.
