The diagnostic group documentation now point to the swift.org URL rather
than the toolchain path, so it no longer needs to be passed all the way
through sourcekitd.
Resolves rdar://151500502.
We shouldn't be attempting to append SourceFiles
to the module after-the-fact for syntactic macro
expansion, refactor things such that the SourceFile
is created alongside the ModuleDecl.
Expand macros in the specified source file syntactically (without any
module imports, nor typechecking).
Request would look like:
```
{
key.compilerargs: [...]
key.sourcefile: <file name>
key.sourcetext: <source text> (optional)
key.expansions: [<expansion specifier>...]
}
```
`key.compilerargs` are used for getting plugins search paths. If
`key.sourcetext` is not specified, it's loaded from the file system.
Each `<expansion sepecifier>` is
```
{
key.offset: <offset>
key.modulename: <plugin module name>
key.typename: <macro typename>
key.macro_roles: [<macro role UID>...]
}
```
Clients have to provide the module and type names because that's
semantic.
Response is a `CategorizedEdits` just like (semantic) "ExpandMacro"
refactoring. But without `key.buffer_name`. Nested expnasions are not
supported at this point.
Driver uses its path to derive the plugin paths (i.e.
'lib/swift/host/plugins' et al.) Previously it was a constant string
'swiftc' that caused SourceKit failed to find dylib plugins in the
toolchain. Since 'SwiftLangSupport' knows the swift-frontend path,
use it, but replacing the filename with 'swiftc', to derive the plugin
paths.

Make a single 'PluginRegistry' and share it between SwiftASTManager,
IDEInspectionInstance, and CompileInstance. And inject the plugin
registry to ASTContext right after 'CompilerInstance.setup()'
That way, all sema-capable ASTContext in SourceKit share a single
PluginRegistry.
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.
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.

We need swiftsourcedocinfo for cursor info and to be able to reuse the ASTContext from code completion for cursor info, we need to also retrieve the sourcedocinfo for code completion requests.
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.
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.
