[PATCH] D57779: [SLP] Add support for throttling.

[Dinar Temirbulatov via Phabricator via llvm-commits]

dtemirbulatov updated this revision to Diff 254269.
dtemirbulatov added a comment.

Rebased, added the following changes:

- removed TreeState from the proposed change since after fixing getInsertCost I could not observe any regressions.
- reduced default number of cost recalculations to 32 after noticing the new approach to find a subtree works efficiently.
- added support for reductions.
