This includes a bunch of fixes. It is not exhaustive but fit my time boxed time
period I set aside to look at this today.
A quick non-exhaustive list:
1. I removed unnecessary verify-additional-prefix lines.
2. Split tests with typechecker error and non-typechecker error components.
3. Removed complete- lines that we used when testing w/without send
non sednable.
4. Translated complete-and-tns- lines to be just complete- since they are just
testing strict-concurrency=complete and we are not testing complete without
send non sendable anymore.
Find all the usages of `--enable-experimental-feature` or
`--enable-upcoming-feature` in the tests and replace some of the
`REQUIRES: asserts` to use `REQUIRES: swift-feature-Foo` instead, which
should correctly apply to depending on the asserts/noasserts mode of the
toolchain for each feature.
Remove some comments that talked about enabling asserts since they don't
apply anymore (but I might had miss some).
All this was done with an automated script, so some formatting weirdness
might happen, but I hope I fixed most of those.
There might be some tests that were `REQUIRES: asserts` that might run
in `noasserts` toolchains now. This will normally be because their
feature went from experimental to upcoming/base and the tests were not
updated.
`TypeChecker::containsProtocol` shouldn't propagate user-provided
`allowMissing` to existential superclass check because the type
could be `& Sendable` and `allowMissing` propagation would result
in invalid builtin conformance returned for a non-conforming
superclass.
This means that:
1. In test cases where minimal is the default (swift 5 without
-warn-concurrency), I added RUN lines for targeted, complete, and complete +
sns.
2. In test cases where complete is the default (swift 6, -warn-concurrency,
specified complete with -strict-concurrency), I added a send non-sendable run
line.
In each of these cases, I added additional expected-* lines as appropriate so
the tests can compile in each mode successfully.
When performing conversions to an existential that involves Sendable,
introducing missing conformances as needed to allow the type-check to
succeed and then (later) they'll be diagnosed appropriately.
