[PATCH] D20143: New pass: guard widening

[Sanjoy Das via llvm-commits]

sanjoy updated this revision to Diff 57689.
sanjoy added a comment.

Use ptrset to avoid exponential behavior, and add test case for it.

(The motivation being that I very quickly ran into a case where a
hoisting threshold of 2 was too small :) )
