Add a platform kind and availability attributes for macCatalyst. macCatalyst
uses iOS version numbers and inherits availability from iOS attributes unless
a macCatalyst attribute is explicitly provided.
in all SourceKit requests.
This validation may call many stat(2). Since we don't expect system files
are edited. Disable it for SourceKit requests. Even if they are edited,
manual builds can validates and updates them.

To controls the lifetime of CompilerInstance within CompletionIntance.
- Prevent from using the same CompilerInstance from multiple completion
requests
- Separate the stacktrace between "fast" and "normal" completions
- Further code consolidation between various completion-like requests
- Introduce ide::CompletionInstance to manage CompilerInstance
- `CompletionInstance` vends the cached CompilerInstance when:
-- The compiler arguments (i.e. CompilerInvocation) has has not changed
-- The primary file is the same
-- The completion happens inside function bodies in both previous and
current completion
-- The interface hash of the primary file has not changed
- Otherwise, it vends a fresh CompilerInstance and cache it for the next
completion

codeCompleteOpen() has own sorting algorithm, codeComplete() calls this
sortCompletionResults() in its callback. So this pre-sorting is
completely unnecessary.
State the previously unstated nested type requirement that CodingKeys adds to the witness requirements of a given type. The goal is to make this member cheap to synthesize, and independent of the expensive protocol conformance checks required to append it to the member list.
Further, this makes a clean conceptual separation between what I'm calling "nested type requirements" and actual type and value requirements.
With luck, we'll never have to use this attribute anywhere else.
SwiftSourceInfo files provide source location information for decls coming from
loaded modules. For most IDE use cases it either has an undesirable impact on
performance with no benefit (code completion), results in stale locations being
used instead of more up-to-date indexer locations (cursor info), or has no
observable effect (live diagnostics, which are filtered to just those with a
location in the primary file).
For non-IDE clients of SourceKit though, cursor info providing declaration
locations for symbols from other modules is useful, so add a global
configuration option (and a new request to set it) to control whether
.swiftsourceinfo files are loaded or not based on use case (they are loaded by
default).
Restore the previous commit which somehow passed the buildbot given a
missing condition on the sub-configure for libdispatch. This makes it
more explicit as to what the desire is; the variable was being used to
serve as a proxy for whether the build is not on a Darwin target.
This flag was being used as an alias for whether or not the host is
non-Darwin. Rather than adding custom checks for this, use the explicit
check that CMake supports. This simplifies the logic and avoids the
proliferation of custom variables which can become confusing for others
who are not familiar with the custom build infrastructure.
It looks like we recently started binding extensions to their nominals in order
to continue to compute access levels via ValueDecl::getFormalAccess() after an
assertion was added to enforce that bindExtensions had been called before
anything tried to call ExtensionDecl::getBoundNominal() - which
getFormalAccess() depends on. Sourcekitd's syntactic requests are made on every
keypress in the editor though, so we shouldn't do any name binding (which may
require module loading) to keep them as fast as possible.
This patch restores the old inferAccessLevel() functions we used prior to the
switch to ValueDecl::getFormalAccess() (plus a few fixes) that does as much as
it can syntactically, without any name binding, and simply doesn't report the
access level in cases where it couldn't be computed without name-binding.
This also fixes an assertion hit we were getting trying to bind extensions in
inactive ifconfig clauses, which ASTScope doesn't support.

This allows us use an OptionSet parameter for
the request (as currently we can't directly use it
as a parameter due to not having an == definition
for it). It also allows us to regain default
arguments for the source loc and flag parameters.
The VFS tests were using Unix absolute paths, which does not play well
when Windows see them as relative to the current drive letter.
By using the temporal directory, both Windows and Unix can use the same
paths and avoid the problem.
Additionally, a couple of inputs have to be transformed into the native
path format, because sourcekitd-test compares the inputs as strings, and
they need to match exactly. So the source file and the name of the VFS
entries are transformed into native using the helper from LLVM support.
Get source locations from '.swiftsourceinfo' is currently expensive.
Since they are not necessary for code completion, set
'IgnoreSwiftSourceInfo' to 'true'.

This removes the custom `LINK_LIBS` in favour of
`target_link_libraries`. This simplifies the custom functions that we
have for adding libraries, makes it easier to query the information from
ninja and will allow us to slowly remove more of the custom logic for
building the products.
GetFinalPathNameByHandleW returns NTPaths (\\?\ Paths) which is an issue
as they don't match the paths stored in the internal dictionaries which
are DOS paths.
- Use `performParseAndResolveImportsOnly()` to invoke the frontend
- Do `bindExtensions()` in `ide::typeCheckContextUntil()`
- Typecheck preceding `TopLevelCodeDecl`s only if the compleiton is in
a `TopLevelCodeDecl`
- Other related tweaks

Patch up all the places that are making a syntactic judgement about the
isInvalid() bit in a ValueDecl. They may continue to use that query,
but most guard themselves on whether the interface type has been set.
Specifically, if the document was re-opened, we would drop the reference
and the call to readSemanticInfo could use-after-free the array of
diagnostics. This manifested as a very rare crash while testing
sourcekit-lsp.
✔ More informative error messages in case of crashes.
✔ Handling and documenting different cases.
✔ Test cases for different cases.
✔ Make SDKDependencies.swift pass again.
TypeCheckPattern used to splat the interface type into this, and
different parts of the compiler would check one or the other. There is
now one source of truth: The interface type. The type repr is now just
a signal that the user has written an explicit type annotation on
a parameter. For variables, we will eventually be able to just grab
this information from the parent pattern.
After setting up the .swiftsourceinfo file, this patch starts to actually serialize
and de-serialize source locations for declaration. The binary format of .swiftsourceinfo
currently contains these three records:
BasicDeclLocs: a hash table mapping from a USR ID to a list of basic source locations. The USR id
could be retrieved from the following DeclUSRs record using an actual decl USR. The basic source locations
include a file ID and the results from Decl::getLoc(), ValueDecl::getNameLoc(), Decl::getStartLoc() and Decl::getEndLoc().
The file ID could be used to retrieve the actual file name from the following SourceFilePaths record.
Each location is encoded as a line:column pair.
DeclUSRS: a hash table mapping from USR to a USR ID used by location records.
SourceFilePaths: a hash table mapping from a file ID to actual file name.
BasicDeclLocs should be sufficient for most diagnostic cases. If additional source locations
are needed, we could always add new source location records without breaking the backward compatibility.
When de-serializing the source location from a module-imported decl, we calculate its USR, retrieve the USR ID
from the DeclUSRS record, and use the USR ID to look up the basic location list in the BasicDeclLocs record.

Structurally prevent a number of common anti-patterns involving generic
signatures by separating the interface into GenericSignature and the
implementation into GenericSignatureBase. In particular, this allows
the comparison operators to be deleted which forces callers to
canonicalize the signature or ask to compare pointers explicitly.
