Infer the `-target` argument to `swift-synthesize-interface` to be the host
triple when unspecified instead of emitting an error.

Since LayoutPrespecialization has been enabled by default in all compiler
invocations for quite some time, it doesn't make sense for it to be treated as
experimental feature. Make it a baseline feature and remove all the
checks for it from the compiler.
AllowDeserializingImplementationOnly was historically added as a defensive
check against deserailzation issues introduced by @implementationOnly imports.
It's no longer specified by other tools, thus the ABI checker should drop
it as well.

Textual interfaces for 'Darwin' built with recent compilers specify that it is built witout C++ interop enabled. However, to ensure compatibility with versions of the 'Darwin' module built with older compilers, we hard-code this fact. This is required to break the module cycle that occurs when building the 'Darwin' module with C++ interop enabled, where the underlying 'Darwin' clang module depends on C++ standard library for which the compiler brings in the 'CxxStdlib' Swift overlay, which depends on 'Darwin'.
Improve diagnostics message for swift caching build by trying to emit
the diagnostics early when there is more context to differentiate the
different kind of problems.
After the improvement, CAS Error should be more closer to when there is
functional problem with the CAS, rather than mixing in other kinds of
problem (like scanning dependency failures) when operating with a CAS.

The Runtime module requires C++ interop enabled, because that's
the only way to robustly fix things so that it is able to declare various
types and constants without clashing with system headers.
To make this work, we also need to add a missing invocation to sil-opt to
make it pick the correct C++ runtime library.

Move the backtracing code into a new Runtime module. This means renaming
the Swift Runtime's CMake target because otherwise there will be a name
clash.

When Swift passes search paths to clang, it does so directly into the HeaderSearch. That means that those paths get ordered inconsistently compared to the equivalent clang flag, and causes inconsistencies when building clang modules with clang and with Swift. Instead of touching the HeaderSearch directly, pass Swift search paths as driver flags, just do them after the -Xcc ones.
Swift doesn't have a way to pass a search path to clang as -isystem, only as -I which usually isn't the right flag. Add an -Isystem Swift flag so that those paths can be passed to clang as -isystem.

Rather than exposing an `addFile` member on
ModuleDecl, have the `create` members take a
lambda that populates the files for the module.
Once module construction has finished, the files
are immutable.
Add a new bits/ header to the Android overlay, include runtime libraries that are
auto-extracted and listed many times to the list of libraries to be de-duplicated,
enable a C++ interop test that's working again, and update the doc with new
libraries that need to be available to run a simple executable.
The `-include-submodules` flag causes the synthesized interface to include
implicit Clang submodules of the module being printed. Since these are
automatically made visible when importing the corresponding top-level module,
it's often useful to have them present in the same synthesized Swift
interface instead of having to make separate invocations to get each
submodule separately.
The `-print-fully-qualified-types` causes type names to be printed with
full module qualification. This is useful when using the synthesized
interface for some other kind of analysis, because it ensures that all
type references explicitly indicate which module they came from, instead
of having to guess scoping and import resolution rules to figure out
which module a reference comes from.
* Make ExportedSourceFile hold any Syntax as the root node
* Move `ExportedSourceFileRequest::evaluate()` to `ParseRequests.cpp`
* Pass the decl context and `GeneatedSourceFileInfo::Kind` to
`swift_ASTGen_parseSourceFile()` to customize the parsing
* Make `ExportedSourceFile` to hold an arbitrary Syntax node
* Move round-trip checking into `ExportedSourceFileRequest::evaluate()`
* Split `parseSourceFileViaASTGen` completely from C++ parsing logic
(in `ParseSourceFileRequest::evaluate()`)
* Remove 'ParserDiagnostics' experimental feature: Now that we have
ParserASTGen mode which includes the swift-syntax parser diagnostics.
This mode is similar to `swift-symbolgraph-extract`; it takes a subset of compiler
flags to configure the invocation for module loading, as well as a module name
whose contents should be extracted. It does not take any other input files. The
output is a single text file specified by `-o` (or `stdout` if not specified).
While the most common use case for this would be viewing the synthesized Swift
interface for a Clang module, since the implementation simply calls
`swift::ide::printModuleInterface` under the hood, it's usable for any module
that Swift can import. Thus, it could also be used to view a synthesized textual
representation of, say, a compiled `.swiftmodule`.
One could imagine that in the future, we might add more flags to
`swift-synthesize-interface` to modify various `PrintOptions` used when
generating the output, if we think those would be useful.
