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.
`@Sendable` on completion handlers imported from Objective-C has been
implemented for a while, but has been disabled in production builds
due to a number of problems we've encountered with rolling it out.
Introduce an experimental feature for `@Sendable` completion handlers
so we can iterate on this more before we enable it by default.
Part of rdar://85569247, which will cover re-landing this feature.
Custom attributes were not printed because they are marked
'UserInaccesible'.
* Make CustomAttr 'RejectByParser' instead of 'UserInaccessible'
* Remove special treatment for Result Builder attributes
* Load implicit modules in module/header interface gen requests

If a method has an `async` variant, the non-`async` variant will now mark its completion handler parameter `@Sendable`. This shouldn't be a breaking change in Swift 5 code since these declarations are automatically `@_predatesConcurrency`.
Also adds:
• Support for `@_nonSendable` on parameters, which can be used to override this implicit `@Sendable`
• Support for `@Sendable` on block typedefs; it's generally going to be a good idea to mark completion block typedefs `@Sendable`.
Fixes rdar://85569247.
The attribute was missing from functions with getters as their async
alternative. Only getters are imported like this, so no need to check
for the other accessors.
Resolves rdar://80612566
Instead of a new attribute `@completionHandlerAsync`, allow the use of
the existing `renamed` parameter of `@available` to specify the
asynchronous alternative of a synchronous function.
No errors will be output from invalid names as `@completionHandlerAsync`
had, but if a function is correctly matched then it will be used to
output warnings when using the synchronous function in an asynchronous
context (as before).
Resolves rdar://80612731
1. Removes gating on -enable-experimental-concurrency.
2. Updates eff. prop tests to remove experimental flag,
and also adjusts some tests slightly to avoid things
that are still behind that flag.
