[PATCH] D30483: [DAG] More aggressively Inline TokenFactors

[Nirav Dave via Phabricator via llvm-commits]

Herald added a reviewer: javed.absar.

Now the anti-aliasing in SelectionDAG is on by default, fold in TokenFactors of
TokenFactors with multiple uses for TFs with relatively small number of chains.

This marginally improves DAG analysis.
