bors 91dbf52af3 Auto merge of #44809 - arielb1:small-scope, r=eddyb ... encode region::Scope using fewer bytes Now that region::Scope is no longer interned, its size is more important. This PR encodes region::Scope in 8 bytes instead of 12, which should speed up region inference somewhat (perf testing needed) and should improve the margins on #36799 by 64MB (that's not a lot, I did this PR mostly to speed up region inference). This is a perf-sensitive PR. Please don't roll me up. r? @eddyb This is based on #44743 so I could get more accurate measurements on #36799.		2017-09-25 12:52:02 +00:00
