Add a new demangler option which excludes a closure's type signature.
This will be used in lldb.
Closures are not subject to overloading, and so the signature will never be used to
disambiguate. A demangled closure is uniquely identifiable by its index(s) and parent.
Where opaque types are involved, the concrete type signature can be quite complex. This
demangling option allows callers to avoid printing the underlying complex nested
concrete types.
Example:
before: `closure #1 (Swift.Int) -> () in closure #1 (Swift.Int) -> () in main`
after: `closure #1 in closure #1 in main`
There were a couple of accesses not guarded by
`CacheMtx`, introduce a couple of methods that
guard them, renaming `getASTProducer` while here.
Also make sure we don't ever insert a producer
after it has been purposefully removed by e.g a
close that removes the cached AST.
We were linking with the newly built `swiftrt.o` when in hosttools mode,
which is wrong because the newly built `swiftrt.o` does not match the
compiler we were using for the `SwiftCompilerSources`.
This manifests as a failure in
`SwiftCompilerSources/Sources/Optimizer/Utilities/Verifier.swift`
because `self is ForwardingInstruction` fails as we can't find the
protocol conformance records.

This is needed in specific Apple internal configurations -- as a result
of the limited applicability, this option is not exposed through
`build-script` on purpose.
Addresses rdar://127014753
Add a fast path to create swift CompilerInstance when it is only used to
replay output when there is a cache hit. The normal `setup` function is
very expensive to call, especially in cache mode to setup inputs, and it
needs to be called once per input file from libSwiftScan API due to the
current caching granularity.
The fast path will only construct the part that is needed for output
replay, including the CAS, the output backend and caching diagnostic
processor.

This change introduces a new compilation target platform to the Swift compiler - visionOS.
- Changes to the compiler build infrastrucuture to support building compiler-adjacent artifacts and test suites for the new target.
- Addition of the new platform kind definition.
- Support for the new platform in language constructs such as compile-time availability annotations or runtime OS version queries.
- Utilities to read out Darwin platform SDK info containing platform mapping data.
- Utilities to support re-mapping availability annotations from iOS to visionOS (e.g. 'updateIntroducedPlatformForFallback', 'updateDeprecatedPlatformForFallback', 'updateObsoletedPlatformForFallback').
- Additional tests exercising platform-specific availability handling and availability re-mapping fallback code-path.
- Changes to existing test suite to accomodate the new platform.
LLVM is gearing up to move to `std::endianness` and as part of that has
moved `llvm::support::endianness` to `llvm::endianness`
(bbdbcd83e6702f314d147a680247058a899ba261). Rename our uses.
`OptTable` was a source of consistent churn due to new arguments to the
`OPTION` macro. LLVM 3f092f37b7362447cbb13f5502dae4bdd5762afd extracted
the handling of the common option parts (eg. an ID and an info) out into
separate macros to reduce this - use those here (since unsurprisingly,
more arguments were added).
Relying on the corresponding field in the '-explicit-swift-module-map-file' provided by the driver.
Only bridging headers require a module map because that's what aids header include resolution. With lazy module loading today, '.modulemap' parsing which happens when instantiating Clang is responsible for associating headers with modules. Then upon encountering a header include inside the bridging header the compiler knows which module corresponds to said header and is then able to load explicitly-provided PCM for that module. For all other module dependencies, they are only ever queried by-name from Swift, so '.modulemap' parsing is not necessary.
