[PATCH] D89264: [LICM] Make promotion faster

[Alina Sbirlea via Phabricator via llvm-commits]

asbirlea added a comment.

I tested this in two configurations we use for compiler releases and I'm seeing quite a few runtime regressions in the 10-20% area and a couple of 40% run time regressions.
It doesn't look worth the compile time gain with such large run time regressions.
