Auto merge of #27943 - arielb1:fast-region, r=nikomatsakis
This increases regionck performance greatly - type-checking on librustc decreased from 9.1s to 8.1s. Because of Amdahl's law, total performance is improved only by about 1.5% (LLVM wizards, this is your opportunity to shine!). before: 576.91user 4.26system 7:42.36elapsed 125%CPU (0avgtext+0avgdata 1142192maxresident)k after: 566.50user 4.84system 7:36.84elapsed 125%CPU (0avgtext+0avgdata 1124304maxresident)k I am somewhat worried really need to find out why we have this Red Queen's Race going on here. Originally I suspected it may be a problem from RFC1214's warnings, but it seems to be an effect from other changes. However, the increase seems to be mostly in LLVM's time, so I guess it's the LLVM wizards' problem. r? @nikomatsakis
