Previously we would skip resolving any solver-based
cursor info in a VarDecl accessor as the VarDecl
source range does not encompass the AccessorDecl.
Avoid looking at the VarDecl source range in this
case.

Add a case for completing type attributes in
inheritance clause position, and limit the
completion of `@unchecked`, `@preconcurrency`, and
`@retroactive` to that case.
Complete ownership specifiers such as `consuming`,
`borrowing`, and `inout` in parameter type
position. While here, also complete `isolated`.

When doing solver-based completion, the request
will fail, avoid falling back to a regular call
expression in that case; we only care about
whether we got the callback.

For unresolved member completion, we were preferring
the more general type, when we ought to be preferring
the more specific type. Additionally, for both
unresolved member and postfix completion we were
opening archetypes, which doesn't work as expected
since we don't compare requirements. Factor out
the logic that deals with merging base types for
lookup, and have it prefer either the subtype, or
the optional type in the case of optional promotion.

`Res.FirstTrailingClosureIndex` is an index into
the argument list, so comparing it against a
parameter index is wrong. Instead, compare it
against the argument index of the completion token,
which is what we want to be checking. This ensures
we don't try and offer argument completions for
non-function default arguments.

Although I don't plan to bring over new assertions wholesale
into the current qualification branch, it's entirely possible
that various minor changes in main will use the new assertions;
having this basic support in the release branch will simplify that.
(This is why I'm adding the includes as a separate pass from
rewriting the individual assertions)
We only set `isDynamic` to `true` if we were inside an expression. Also set `isDynamic` when we are performing cursor info at an overridable declaration. This allows jump-to-definition to jump to declarations that override the one that we performed cursor info on.

This warnings don't give much benefits for developers. Code completion
UI tends to show them unusable. But usually, developers can modify the
context to accept async calls, e.g. by wrapping it with `Task { }`

This change is two fold. Firstly it enables collection of exported
imports from non source file units. Additionally this recurses through
the exported imports to ensure the transitive set is collected.

To compute the expected type of a call pattern (which is the return type of the function if that call pattern is being used), we called `getTypeForCompletion` for the entire call, in the same way that we do for the code completion token. However, this pattern does not generally work. For the code completion token it worked because the code completion expression doesn’t have an inherent type and it inherits the type solely from its context. Calls, however, have an inherent return type and that type gets assigned as the `typeForCompletion`.
Implement targeted checks for the two most common cases where an expected type exists: If the call that we suggest call patterns for is itself an argument to another function or if it is used in a place that has a contextual type in the constraint system (eg. a variable binding or a `return` statement). This means that we no longer return `Convertible` for call patterns in some more complex scenarios. But given that this information was computed based on incorrect results and that in those cases all call patterns had a `Convertible` type relation, I think that’s acceptable. Fixing this would require recording more information in the constraints system, which is out-of-scope for now.
This change introduces a new compilation target platform to the Swift compiler - visionOS.
- Changes to the compiler build infrastrucuture to support building compiler-adjacent artifacts and test suites for the new target.
- Addition of the new platform kind definition.
- Support for the new platform in language constructs such as compile-time availability annotations or runtime OS version queries.
- Utilities to read out Darwin platform SDK info containing platform mapping data.
- Utilities to support re-mapping availability annotations from iOS to visionOS (e.g. 'updateIntroducedPlatformForFallback', 'updateDeprecatedPlatformForFallback', 'updateObsoletedPlatformForFallback').
- Additional tests exercising platform-specific availability handling and availability re-mapping fallback code-path.
- Changes to existing test suite to accomodate the new platform.
Generated interfaces for Clang modules used to try printing normal
comments between decls extracted from the header text. That was because
doc-comment was not common in C/ObjC headers. But mainly because of
"import as member feature" Clang decls aren't printed in the order as
they appear in the header file, the logic determinig which comment
belongs to which decl was not working property. We've decided to remove
that feature and only print the proper doc-comments as it has been
getting common.

This has two benefits:
1. We can now report ambiguous variable types
2. We are more robust in the generation of results for declarations inside closures. If the closure has an error, we won’t apply the solution to the AST and thus any cursor info that tried to get types out of the AST would fail.

LLVM is presumably moving towards `std::string_view` -
`StringRef::startswith` is deprecated on tip. `SmallString::startswith`
was just renamed there (maybe with some small deprecation inbetween, but
if so, we've missed it).
The `SmallString::startswith` references were moved to
`.str().starts_with()`, rather than adding the `starts_with` on
`stable/20230725` as we only had a few of them. Open to switching that
over if anyone feels strongly though.
