[PATCH] D68414: [SROA] Enhance AggLoadStoreRewriter to rewrite integer load/store if it covers multi fields in original aggregate

[Guozhi Wei via Phabricator via llvm-commits]

Carrot added a comment.

This version splits overlapped AllocaSlices like

  S1   ------
  S2      ------

into

  S11  ---
  S12     ---
  S2      ------

So later these slices can be rewritten with scalar operations.
