After rust-lang#43252 is merged, building stage0 libcore with -i (--incremental) flag will cause 17 "Quasi-quoting might make incremental compilation very inefficient: NtExpr(..)" warnings, as in rust-lang#40946. Fixing the warning in rust-lang#40946 will take 12 weeks from now to make into the next stage0, so it is quicker to workaround it in libcore instead.
