[swift-evolution] [Review] SE-0102: Remove @noreturn attribute and introduce an empty NoReturn type

[Shawn Erickson]

Curious on the possibility of something like the following to denote a no
return function?

func foo() -> !

...or mostly joking...

func foo() ->💥 (for thing like fatalError)
func foo() -> 🔃(for things like dispatch main)

Anyway I am generally -0.5 on this change without understanding if this
could be a bottom type and how that could work in the bigger picture.
