The two new states are None & Indeterminate.
The former means "no such object", and "indeterminate" represents
an uninitialized object.
As the clang importer was using these only to cover a switch of
unhandled case, this should be functionally equivalent to what
was there before.
When we remove Sema's UsedConformances list, conformances to _BridgedStoredNSError
are checked from SILGen, where its too late to check function bodies of synthesized
functions.
We could solve this by adding a callback to type check a synthesized function's
body, but in fact all synthesized functions are rather trivial so it's better to
build their bodies fully type checked.
Start by building fully checked expressions for various accessors in ClangImporter.
Way back in Swift 1 I was trying to draw a distinction between
"overlays", separate libraries that added Swift content to an existing
Objective-C framework, and "the Swift part of a mixed-source
framework", even though they're implemented in almost exactly the same
way. "Adapter module" was the term that covered both of those. In
practice, however, no one knew what "adapter" meant. Bring an end to
this confusion by just using "overlay" within the compiler even for
the mixed-source framework case.
No intended functionality change.
This allows the conversion of the Windows `BOOL` type to be converted to
`Bool` implicitly. The implicit bridging allows for a more ergonomic
use of the native Windows APIs in Swift.
Due to the ambiguity between the Objective C `BOOL` and the Windows
`BOOL`, we must manually map the `BOOL` type to the appropriate type.
This required lifting the mapping entry for `ObjCBool` from the mapped
types XMACRO definition into the inline definition in the importer.
Take the opportunity to simplify the mapping code.
Adjust the standard library usage of the `BOOL` type which is now
eclipsed by the new `WindowsBool` type, preferring to use `Bool`
whenever possible.
Thanks to Jordan Rose for the suggestion to do this and a couple of
hints along the way.
* Moves the IsStatic flag from VarDecl to AbstractStorageDecl.
* Adds a StaticSubscriptKind to SubscriptDecl.
* Updates serialization for these changes.
* Updates SubscriptDecl constructor call sites for these changes.
Refactor the PlatformAvailability logic for determining
which Clang availability attributes are relevant when importing. The goal
is to separate the logic for attribute relevance for a given platform from
the logic to determine whether a deprecated attribute should be imported as
unavailable in Swift.
This also makes it possible for the "deprecated-as-unavailable" logic to
refer to the underlying Clang declaration, which is functionality that will
be used in a later commit.
This commit has no intended functional change.

The getLocStart API is deprecated and slated for removal from LLVM
very soon. Switch to use getBeginLoc instead. I did not see any uses
of the corresponding getLocEnd API.
This refactoring uses large portions of the already existing code for
x86_64 and s390 to implement AAPCS64 __VaListBuilder. The parts where
each implementation differ are the x86_64 header, and the order of the
general and vector registers.
The changes also addresses many of the request from the reviewers in
#20862 which were not addressed originally, like the reuse of the
already existing code, and the generalizations for the code to be useful
for platforms different than Linux (Android, for example).
Sema would directly check for the presence of the @objcMembers attribute,
and inherit it from the immediate superclass in validateDecl().
We don't want validateDecl() to have side effects like this and this was
already a problem, because it would not inherit the attribute transitively
in some cases.
Instead, add a ClassDecl::hasObjCMembers() method that walks over all
ancestors and caches the result.

We've been running doxygen with the autobrief option for a couple of
years now. This makes the \brief markers into our comments
redundant. Since they are a visual distraction and we don't want to
encourage more \brief markers in new code either, this patch removes
them all.
