Craig Topper 62d0c01c2c [SelectionDAG] Remove pointer from MMO for VP strided load/store. (#82667) ...

MachineIR alias analysis assumes that only bytes after the pointer will
be accessed. This is incorrect if the stride is negative.

This is causing miscompiles in our downstream after SLP started making
strided loads.

Fixes #82657
