Solver based results are fast within a function, where the `ASTContext`
can be re-used. But it is significantly slower than the AST based
results when outside of a function. Instead of using solver based as the
primary results, only use them as a fallback for when AST based fails.

Pass back the original location (ie. where the macro was expanded, not
the location that the generated code would be inserted) for cursor info
and indexing. Also mark any declarations/references within generated
source as implicit.

Update to have a single refactoring collection method for cursor
refactorings and another for ranges. The various functions were only
needed because of the extra availability information on renames, so just
give that to all refactorings.
Update requests to handle being passed a separate `key.primary_file`
which specifies the file to use for building the AST. `key.sourcefile`
is then the file to find in `SourceManager`, which could be a generated
buffer.
Resolves rdar://106863186.
This hooks up the cursor info infrastructure to be able to pass through multiple, ambiguous results. There are still minor issues that cause solver-based cursor info to not actually report the ambiguous results but those will be fixed in a follow-up PR.
Rather than using `ModuleDecl::isSystemModule()` to determine whether a
module is not a user module, instead check whether the module was
defined adjacent to the compiler or if it's part of the SDK.
If no SDK path was given, then `isSystemModule` is still used as a
fallback.

Retrieving local rename ranges and the local rename refactoring both had
almost identical methods, except for the addition of retrieving the
outermost shadowed decl that was added a couple months back. Merge them.
Resolves rdar://106529370.
This adds a new `primary_file` key, which defaults to `sourcefile`. For
nested expansions, `primary_file` should be set to the containing file
and `sourcefile` to the name of the macro expansion buffer.
`source.request.activeregions` is a new request that reports all
`#if`, `#else` and `#elseif` decls in the response with an `is_active` flag.
This is mainly useful for a client to know which branches are active,
but for completeness sake, the active decls are also reported.
Note: it only reports the positions of the decls, not the entire ranges.
It's up to clients to map this to the syntactic structure of a tree.
Reporting the ranges of the decls could be confusing in the case
of nested `#if`s, where the ranges can overlap.
Various requests expect to be walking over the current source file.
While we could add checks to all these to skip decls outside of the
current buffer, it's a little nicer to handle this during the walk
instead.
Allow ignoring nodes that are from macro expansions and add that flag to
the various walks that expect it.
Also add a new `getOriginalAttrs` that filters out attributes in
generated source.
This allows us to model the `ResolvedCursorInfo` types as a proper type hierarchy instead of having to store all values in the base `ResolvedCursorInfo` type.

Macro expansion buffers, along with other generated source buffers,
need more precise "original source ranges" that can be had with the
token-based `SourceRange`. Switch over to `CharSourceRange` and provide
more thoughtfully-determined original source ranges.
Running the SourceKit stress tester with verification of solver-based cursor info returned quite a few differences but in all of them, the old AST-based implementation was actually incorrect. So, instead of verifying the results, deliver the results from solver-baesd cursor info and only fall back to AST-based cursor info if the solver-based implementation returned no results.
rdar://103369449
The main problem that prevented us from reusing the ASTContext was that we weren’t remapping the `LocToResolve` in the temporary buffer that only contains the re-parsed function back to the original buffer. Thus `NodeFinder` couldn’t find the node that we want to get cursor info for.
Getting AST reuse to work for top-level items is harder because it currently heavily relies on the `HasCodeCompletion` state being set on the parser result. I’ll try that in a follow-up PR.
rdar://103251263
This allows us to mark expected deviations between the AST-based and the solver-based implementation in the stress tester as XFails without breaking actual clients
We always verify if a cursor info request is issued through `sourcekitd-test`.
Update rename to pull the outermost-declaration so that references are correctly found.
Rather than keeping suppressed locations in the current parent, keep
them for the whole index. Local rename starts the lookup from the
innermost context it can, which could be a closure. In that case there
is no parent decl on the stack and thus no where to store the locations
to suppress. We could have a specific store for this case, but there
shouldn't be that many of these and they're relatively cheap to store
anyway.

This brings up the ability to compute cursor info results using the completion-like type checking paradigm, which an reuse ASTContexts and doesn’t need to type check the entire file.
For now, the new implementation only supports cursor info on `ValueDecl`s (not on references) because they were easiest to implement. More cursor info kinds are coming soon.
At the moment, we only run the new implementation in a verification mode: It is only invoked in assert toolchains and when run, we check that the results are equivalent to the old implementation. Once more cursor info kinds are implemented and if the SourceKit stress tester doesn’t find any verification issues, we can enable the new implementation, falling back to the old implementation if the new one didn’t produce any results.
This way, each kind of `ResolvedCursorInfo` can define its own set of properties and it’s obvious which properties are used for which kind. Also switch to getters and setters because that makes it easier to search for usages of properties by looking at the call hierarchy of the getter / setter.
`getValue` -> `value`
`getValueOr` -> `value_or`
`hasValue` -> `has_value`
`map` -> `transform`
The old API will be deprecated in the rebranch.
To avoid merge conflicts, use the new API already in the main branch.

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'

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)
`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.

When a variable is re-declared using shorthand syntax (`[foo]` closure capture or `if let foo {`), the user doesn’t perceive this as a new variable declaration. Thus, we should return the original declaration as a secondary result.

This currently doesn't check for inherited docs, ie. either the
imported declaration has docs or it doesn't. There's also a few odd
cases with mixed doc types and when each line is prefixed with '*', but
it's good enough for an initial implementation.
Moves UTF8 sanitisation out of ASTPrinter.h and into Unicode.h so that
it can be used here as well.

Only declarations in the same module as synthesized extension's target
are placed within a synthesized extension. We should thus not add
"::SYNTHESIZED::" to the USR if the given declaration is in a different
and.
As an example, `Foundation` adds a method `components(separatedBy:)` to
`String` through an extension on `StringProtocol`. But since it is
within `Foundation` and not `Swift` it will *not* be in a synthesized
extension of `String` or `StringProtocol`. So it should not have
"::SYNTHESIZED::" added and should also not being in the `String` group.
