Refactor object-safety into its own (cached) module so that we can check it more easily; also extend object safety to cover sized types as well as static methods. This makes it sufficient so that we can always ensure that `Foo : Foo` holds for any trait `Foo`. 2014-12-16 02:11:09 +00:00			`// Check that we correctly prevent users from making trait objects`

Make RFC 1214 warnings into errors, and rip out the "warn or err" associated machinery. Future such attempts should go through lints anyhow. There is a fair amount of fallout in the compile-fail tests, as WF checking now occurs earlier in the process. 2015-12-15 09:31:58 +00:00			`t`
