Ensure that we link `swift_CompilerPluginSupport` into the compiler and
SourceKit, and set the rpath appropriately to find the library in its
installed location.
A number of driver tests copy the driver executable into a temporary
directory to isolate it from the build tree. Also copy the plugin
support library into its appropriate place near the driver executable
to ensure these tests keep working. To help with this, add a
`swift_swift_parser` lit feature, which we can use in tests that
involve the new parser's capabilities.
`getValue` -> `value`
`getValueOr` -> `value_or`
`hasValue` -> `has_value`
`map` -> `transform`
This change does not cover all uses of the old API. Other warnings are worked around in llvm by https://github.com/apple/llvm-project/pull/5618

IDE/Refactoring had dependencies to libswiftIndex, but libswiftIndex
also depends on libswiftIDE (SourceEntityWalker, etc.)
To break libswiftIndex <-> libswiftIDE dependency cycle, move
"refactoring" related files to a new library 'libswiftRefactoring'

These libraries formed a strongly connected component in the CMake build graph. The weakest link I could find was from IDE to FrontendTool and Frontend, which was necessitated by the `CompileInstance` class (https://github.com/apple/swift/pull/40645). I moved a few files out of IDE into a new IDETools library to break the cycle.
Only introduce it and its dependency when the new Swift parser is being
built, and rely more on existing logic to make sure we get the right
build/link flags.
This includes:
- bumping the SWIFT_SYMBOLGRAPH_FORMAT_MINOR version
- introduction of the "swift.extension" symbol and "extensionTo" relationship
- adding support for ExtensionDecl to the Symbol class
- adding a "typeKind" field to the symbol's extension mixin which indicates what kind
of symbol was extended
- intoduction of the -emit-extension-block-symbols flag, which enables the behavior
outlined below
- adaptions to SymbolGraphASTWalker that ensure a swift.extension symbol is emitted
for each extension to a type that does not exist in the local symbol graph
- adaptions to SymbolGraph and SymbolGraphASTWalker that ensure member and conformance
relationships are correctly associated with the swift.extension symbol instead of
the original type declaration's (extended nominal's) symbol where applicable
- adaptions to SymbolGraphASTWalker that ensure swift.extension symbols are connected
to their respective extended nominal's symbol using an extensionTo relationship
Testing:
- adds SymbolGraph tests that test behavior only relevant in
-emit-extension-block-symbols mode
- adapts some SymbolGraph tests to additionally test similar behavior for
extensions to external types in -emit-extension-block-symbols mode
- adapts some SymbolGraph tests to (additionally or exclusively) test the
behavior with -emit-extension-block-symbols mode enabled
Bugfixes:
- fixes a bug where some conformsTo relationships implicated by the conformances
declared on an extension to an external type were not emitted
(see test/SymbolGraph/Relationships/ConformsTo/Indirect.swift)
Further changes:
- documents the strategy for naming and associating children declared in extensions
to typealiases (see test/SymbolGraph/Relationships/MemberOf/Typealias.swift,
test/SymbolGraph/Symbols/Names.swift)
Replace the use of bool and pointer returns for
`walkToXXXPre`/`walkToXXXPost`, and instead use
explicit actions such as `Action::Continue(E)`,
`Action::SkipChildren(E)`, and `Action::Stop()`.
There are also conditional variants, e.g
`Action::SkipChildrenIf`, `Action::VisitChildrenIf`,
and `Action::StopIf`.
There is still more work that can be done here, in
particular:
- SourceEntityWalker still needs to be migrated.
- Some uses of `return false` in pre-visitation
methods can likely now be replaced by
`Action::Stop`.
- We still use bool and pointer returns internally
within the ASTWalker traversal, which could likely
be improved.
But I'm leaving those as future work for now as
this patch is already large enough.
Basic should not be allowed to link Parse, yet it was doing so
to allow Version to provide a constructor that would conveniently
parse a StringRef. This entrypoint also emitted diagnostics, so it
pulled in libAST.
Sink the version parser entrypoint down into Parse where it belongs
and point all the clients to the right place.
Refactor the logic so to have a single target to reference the
compatibility libraries for the host, and use that when needed.
The main driver for this change is supporting the cross-compilation of
x86-64 on Apple Silicon.

`typealias` is currently allowed to refer to a protocol without the `any` keyword. This breaks mangling the typealias type into a USR will crash because parameterized protocols are expected to be `any` types.
Implement a SourceKit-specific minimal workaround for that problem by not computing USRs for parameterized protocols.

This enables the ability to cancel requests, which aren’t code completion requests, again.
Previous crashes in SILGen are prevented by disabling cancellation during the SIL stages. Instead, we add dedicated cancellation checkpoints before and after SIL.

If a 'nil' literal occurs in a swift-case statment, it gets replaced by a reference to 'Optional.none' in the AST. We want to continue highlighting 'nil' as a keyword and not as an enum element.

When an function has an async alternative, that should be preferred when we are completing in an async context. Thus, the sync method should be marked as not recommended if the current context can handle async methods.

Store whether a result is async in the `ContextFreeCodeCompletionResult` and determine whether an async method is used in a sync context when promoting the context free result to a contextual result.
