Fixes #20828
This has no effect on self-check, but improves edge cases involving self-types and protocols where currently performance is very bad. For example,
altairshould be ~2x faster. Two things here:bind_self_fast()in situations wheretype_checkeris not set (e.g. late stages of semantic analysis).bind_self()is required.cc @JukkaL
