[PATCH] D20143: New pass: guard widening

[Andrew Trick via llvm-commits]

IMO this seems as good a form as any for being in-tree, and I think it makes sense to have in-tree given that it's really part of the implementation of the guard intrinsic. You could "hide" the code in other passes, but it's still specific to your compiler until others start using the intrinsic. This way, the experimental feature is self-contained.

Also, I'm curious how integrating it with other passes would actually improve the compile time.

If you're talking about adding this pass to the standard pipeline, that's a different story.
