  -----------
  [SLP] Support memory runtime alias checks

Vectorize straight-line code blocked by runtime-checkable may-alias
dependencies by versioning the block. Drop the deps, and if the tree is
profitable, emit base-object address-range overlap checks branching to a
vector fast path or an original-order scalar fallback.

Fixes #201534
