Most `SemaAnnotator`s don’t actually care about the char source range. Instead, they only care about the start location of the reference, which is also included in `SourceRange`. Computing a `CharSourceRange` from a `SourceRange` is kind of expensive because it needs to start a new lexer.
To avoid this overhead, pass `SourceRange` to `SemaAnnotator::passReference` and related functions and let the clients compute the `CharSourceRange` when needed.
This reduces the overhead of index-while-building by about 10%.
If a module has the same `public-module-name` as the module being
generated and its import is exported, merge it into the same generated
interface.
Fix various always-imported modules from being printed while here and
update all the tests that checked for them.

The underlying type for a typealias can be an unbound generic type,
replace these with the bound generic equivalent. This avoids crashing
when attempting to compute the type relation (in the future we'll
want to open these type parameters for the comparison).

Raw identifiers are backtick-delimited identifiers that can contain any
non-identifier character other than the backtick itself, CR, LF, or other
non-printable ASCII code units, and which are also not composed entirely
of operator characters.
The new `DECL_ATTR_FEATURE_REQUIREMENT` macro in DeclAttr.def can be used to declare that an attribute should only be available when a related language feature is enabled.
Effects:
• `#if hasAttribute(someAttr)` will return `false` unless the required feature is enabled.
• Code completion will not include the attribute unless the required feature is enabled.
• `TypeChecker::checkDeclAttributes()` diagnoses non-implicit uses of the attribute.
Add this mechanism and use it to tie @abi to the ABIAttribute feature. Also design tests for it.
The previous logic for this was unused, replace
it with new logic that consults
InvertibleProtocols.def for the list of protocols
to suggest.

Use a worklist instead, and bump the size of the
inline set storage. This shaves ~30ms off the
time it takes to do this cached completion:
```
import SwiftUI
Table(#^CC^#
```
The "buffer ID" in a SourceFile, which is used to find the source file's
contents in the SourceManager, has always been optional. However, the
effectively every SourceFile actually does have a buffer ID, and the
vast majority of accesses to this information dereference the optional
without checking.
Update the handful of call sites that provided `nullopt` as the buffer
ID to provide a proper buffer instead. These were mostly unit tests
and testing programs, with a few places that passed a never-empty
optional through to the SourceFile constructor.
Then, remove optionality from the representation and accessors. It is
now the case that every SourceFile has a buffer ID, simplying a bunch
of code.
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`.

We treated enum case parameters the same way as function parameters and weren’t considering that they can be unlabeled. That caused us to insert eg. `_ ` in front of the case’s type, producing `case myCase(_ String)`, which is invalid. When we are inside an enum case parameter and the parameter label is empty, treat it the same as a function call, which will leave the label untouched if it isn’t modified and insert a label including a colon if a new label is introduced.

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.

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 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.

SourceKit-LSP currently parses the XML comment to generate Markdown again but round-tripping a (probably markdown) doc comment to XML to Markdown is lossy in many cases and unnecessary work. Include the comment as it is spelled in source in the cursor info response so that sourcekit-lsp can display it.
