[PATCH] D55988: WIP: RegBankSelect: Support some more complex part mappings

[Matt Arsenault via Phabricator via llvm-commits]

arsenm updated this revision to Diff 179463.
arsenm added a comment.

Cleanup a bit, fix greedy, and support vectors.

I have a few more partial patches to support preserving the original vector types (which I might have use for) and for irregularly sized breakdowns (which I don't). Introducing more instructions makes the current handling for multiple insert points more complicated (and there are no tests in tree which actually hit this, so I still don't understand what it would mean)
