  -----------
  [SLP]Support runtime alias checks versioning for blocks in loops

Allow versioning of blocks inside loops, e.g. fully unrolled inner loop,
whose pointers are advanced by the loop header PHIs. Accept header PHIs
as base objects, use the base values directly in the bounds instead of
recomputing loop-variant bases from their recurrences.

Fixes #49896
