Auto merge of #24615 - arielb1:rapid-reject, r=nikomatsakis
skolemize_late_bound_regions essentially copies the entire type (most of the times it shouldn't, but it does), and match_impl runs millions of times. Times compiling rustc, tested with $ make -j4 rustc-stage1 $ ( time RUSTFLAGS=-Z time-passes make -j4 rustc-stage2 ) # need LLVM time for calibration Before: real 21m44.960s user 29m38.812s sys 0m14.944s After: real 19m31.445s user 26m47.260s sys 0m14.952s Making this is a 10% performance improvement. LLVM passes took 867 seconds before, 862 seconds after.
