[PATCH] D105516: [clang][PassManager] Add -falways-mem2reg to run mem2reg at -O0

[Eli Friedman via Phabricator via cfe-commits]

I think it would be better to focus on making -O1 more usable for this sort of purpose, rather than introduce -O0.5.  I mean, there's a lot of wiggle-room between -O0 and -O2, but I don't think it makes sense to add a driver option that promises to run exactly one optimization.
