8578584f61 Implementations for operators and async functions on AsyncSequence per SE-0298 (#35740)
* Implementations for operators and async functions on AsyncSequence per SE-0298

* Add trailing new lines to AsyncSequence adopter files

* Remove extra // from preambles

* Transition sequence properties and sequence initializers to internal

* Rename Upstream to Base

* Rename "Failable" asynchronous sequences to "Throwing"

* Make iteration consistent with closure lifetimes and track failure via state

* Use for await syntax for async function extensions on AsyncSequence

* Work-around rethrows calculations being incorrect for conformance + closure rethrowing

* Update testing names to reflect Throwing versus Failable

* Incorperate runAsyncAndBlock into the test function for suite calls

* Remove @frozen from AsyncSequence operators

* Back out reduce family functions for now due to IRGen bug

* Additional corrections for throwing cases and fix up potential linux crasher

* Add a upstream and throwing tests and correct flatMap's throwing behavior

* Unify parameter names to count

* Add a more helpful precondition on prefix

* Add tests for throwing cases of non closure async functions on AsyncSequence

* Correct missing count transition in dropFirst

* Correct missing , in assertion

* [NFC] add commentary on optimization in dropFirst on dropFirst

* Disable collect tests for non macOS platforms for now

* Disable all async sequence tests for non macOS platforms for now

6e05240426 AsyncSequence and protocol conformance rethrows (#35224)
* Initial draft of async sequences

* Adjust AsyncSequence associated type requirements

* Add a draft implementation of AsyncSequence and associated functionality

* Correct merge damage and rename from GeneratorProtocol to AsyncIteratorProtocol

* Add AsyncSequence types to the cmake lists

* Add cancellation support

* [DRAFT] Implementation of protocol conformance rethrowing

* Account for ASTVerifier passes to ensure throwing and by conformance rethrowing verifies appropriately

* Remove commented out code

* OtherConstructorDeclRefExpr can also be a source of a rethrowing kind function

* Re-order the checkApply logic to account for existing throwing calculations better

* Extract rethrowing calculation into smaller functions

* Allow for closures and protocol conformances to contribute to throwing

* Add unit tests for conformance based rethrowing

* Restrict rethrowing requirements to only protocols marked with @rethrows

* Correct logic for gating of `@rethrows` and adjust the determinates to be based upon throws and not rethrows spelling

* Attempt to unify the async sequence features together

* Reorder try await to latest syntax

* revert back to the inout diagnosis

* House mutations in local scope

* Revert "House mutations in local scope"

This reverts commit d91f1b25b59fff8e4be107c808895ff3f293b394.

* Adjust for inout diagnostics and fall back to original mutation strategy

* Convert async flag to source locations and add initial try support to for await in syntax

* Fix case typo of MinMax.swift

* Adjust rethrowing tests to account for changes associated with @rethrows

* Allow parsing and diagnostics associated with try applied to for await in syntax

* Correct the code-completion for @rethrows

* Additional corrections for the code-completion for @rethrows this time for the last in the list

* Handle throwing cases of iteration of async sequences

* restore building XCTest

* First wave of feedback fixes

* Rework constraints checking for async sequence for-try-await-in checking

* Allow testing of for-await-in parsing and silgen testing and add unit tests for both

* Remove async sequence operators for now

* Back out cancellation of AsyncIteratorProtocols

* Restructure protocol conformance throws checking and cache results

* remove some stray whitespaces

* Correct some merge damage

* Ensure the throwing determinate for applying for-await-in always has a valid value and adjust the for-await-in silgen test to reflect the cancel changes

* Squelch the python linter for line length
