Move const trait bounds checks to MIR constck Fixes #109543. When checking paths in HIR typeck, we don't want to check for const predicates since all we want might just be a function pointer. Therefore we move this to MIR constck and check that bounds are met during MIR constck. 2023-03-24 09:17:51 +00:00			`//~^ ERROR the trait bound`
