Fixe a couple of bugs in libSyntax parsing found by enabling `-verify-syntax-tree` for `%target-build-swift`:
- Fix parsing of the `actor` contextual keyword in actor decls
- Don't build a libSyntax tree when parsing the availability macro
- The availability macro is not part of the source code and doesn't form a valid Swift file, thus creation of a libSyntax tree is completely pointless and will fail
- Add support for parsing `@_originallyDefinedIn` attributes.
- Add support for parsing `#sourceLocation` in member decl lists
- Add support for effectful properties (throwing/async getters/setters)
- Add support for optional types as the base of a key path (e.g. `\TestOptional2?.something`)
- Allow platform restrictions without a version (e.g. `_iOS13Aligned`)
This workaround to remove legacy architectures from the .a's can fail.
When that happens, it usually means i386 was not among any of the slices
to begin with, so just copy the library out to its destination.
We were only keeping track of `RawSyntax` node IDs to incrementally transfer a syntax tree via JSON. However, AFAICT the incremental JSON transfer option has been superceeded by `SyntaxParseActions`, which are more efficient.
So, let’s clean up and remove the `RawSyntax` node ID and JSON incremental transfer option.
In places that still need a notion of `RawSyntax` identity (like determining the reused syntax regions), use the `RawSyntax`’s pointer instead of the manually created ID.
In `incr_transfer_round_trip.py` always use the code path that uses the `SyntaxParseActions` and remove the transitional code that was still using the incremental JSON transfer but was never called.
Introduce a new parameter `--skip-llbuild-clean` to prevent this from
happening.
This mimicks similar logic in place for `swiftpm`, `swift-driver`
(#33563) and `xctest` (#19512)

Cursor info for a constructor would previously give the cursor info for
the containing type only. It now also adds cursor info for the
constructor itself in a "secondary_symbols" field.
Refactor `passCursorInfoForDecl` to use a single allocator rather than
keeping track of positions in a buffer and assigning everything at the
end of the function.
Refactor the various available refactoring gathering functions to take a
SmallVectorImpl and to not copy strings where they don't need to.

Add more relevant instructions to dump in MemBehaviorDumper.
Therefore the -enable-mem-behavior-dump-all option can be removed.
Also mem-behavior-all.sil into mem-behavior.sil, because the sil-opt command lines don't differ anymore.
Sometimes with the --sccache flag passed to build-script, the first
round of compiler invocations will time-out waiting for the sccache
server to start. Here we ensure the server is started ahead of time
to avoid this failure.

Adds two new fields to the cursor info response:
1. is_dynamic: whether a call is dynamic
2. receivers: receivers of the call (USRs)
Users of the CursorInfo request can use "is_dynamic" to decide whether
to lookup overrides or not, and then the "receivers" as the starting
point of the lookup.

Instead, only reference count the SyntaxArena that the RawSyntax nodes
live in. The user of RawSyntax nodes must guarantee that the SyntaxArena
stays alive as long as the RawSyntax nodes are being accessed.
During parse time, the SyntaxTreeCreator holds on to the SyntaxArena
in which it creates RawSyntax nodes. When inspecting a syntax tree,
the root SyntaxData node keeps the SyntaxArena alive. The change should
be mostly invisible to the users of the public libSyntax API.
This change significantly decreases the overall reference-counting
overhead. Since we were not able to free individual RawSyntax nodes
anyway, performing the reference-counting on the level of the
SyntaxArena feels natural.
* Make the `build-parser-lib` script more flexible on how it finds the llvm source path
* Make sure `swift-syntax-parser-test` can be built even though the script disables building for testing
* Fix a linker error for parser-only build
