[PATCH] D88893: [SROA] Only generate memcpy if the slices is large 'enough' (WIP).

[Roman Lebedev via Phabricator via llvm-commits]

lebedev.ri added a comment.

Personally honestly i'm not so much not okay with doing this in SROA,
but it's that i'm uneasy about introduction of a new TTI dependency to some pass.
Because that implicitly changes it from being a target-independent pass
into being a cost-model driven transform, with rest of transforms
in the pass being "forgotten" to be costmodelled.
