[PATCH] D16057: [SROA] Fix for PR25873: Pre-splitting should always preserve the partition structure.

[Andrea Di Biagio via llvm-commits]

andreadb updated this revision to Diff 46768.
andreadb added a comment.

Patch updated based on Chandler's review comments.

I have added a map from stores to slices. That map is populated when we initially scan through the slices of the alloca in 'presplitLoadsAndStores'.
I have also simplified the code adding an early continue as suggested.

Please let me know if this is ok to commit.

Thanks!
Andrea
