  -----------
  [VPlan] Support pointer min/max bounds in VPlan memory runtime checks. (#225828)

Expand pointer-typed SCEV min/max expressions in VPSCEVExpander as
icmp + select (including profile metadata), matching SCEVExpander.

This allows modeling memory runtime checks with pointer min/max bounds
in VPlan, e.g. for accesses with a runtime stride of unknown sign.

Depends on https://github.com/llvm/llvm-project/pull/221483
