Untyped throws depends on existentials (`any Error`), and is therefore not available in Embedded Swift. Introduce a diagnostic that diagnoses any use of untyped throws, suggesting that one use typed throws instead. Make this an opt-in diagnostic enabled with `-Wwarning EmbeddedRestrictions`, whether in Embedded Swift or not, using the "default ignore" flag on these new warnings. Document this new diagnostic group, and put the existing Embedded Swift error about weak/unowned references in it as well. Part of the general push to have the type checker identify code that will not compile as Embedded Swift earlier, rdar://133874555.
