Hamish Knight 9d4a78678a [Sema] Add logic to diagnose regex feature availability ...

Add the necessary compiler-side logic to allow
the regex parsing library to hand back a set of
features for a regex literal, which can then be
diagnosed by ExprAvailabilityWalker if the
availability context isn't sufficient. No tests
as this only adds the necessary infrastructure,
we don't yet hand back the features from the regex
parsing library.
