Fixes #82279
We don't want to be emitting errors inside of is_const_evaluatable because we may call this during selection where it should be able to fail silently
There were two errors being emitted in
is_const_evaluatable
. The one causing the compile error in #82279 was inside the match arm forFailureKind::MentionsParam
but I moved the other error being emitted too since it made things cleaner imoThe
NotConstEvaluatable
enum *should* have a fourth variant for when we fail to evaluate a concrete const, e.g.0 - 1
but that cant happen until #81339cc @oli-obk @lcnr
