8febd3fb32 Reimplement ModuleDecl::getSourceFileContainingLocation() using SourceManager 
ModuleDecl kept track of all of the source files in the module so that it
could find the source file containing a given location, which relied on
a sorted array all of these source files. SourceManager has its own
similar data structure for a similar query mapping the locations to
buffer IDs.

Replace ModuleDecl's dats structure with a use of the SourceManager's version
with the mapping from buffer IDs to source files.

16e012bb5e [cxx-interop] Teach importer to interpret lifetimebound annotations 
The lifetimebound annotations are now imported as lifetime dependencies.
This works for basic cases but there are still some parts missing:
* Support lifeitmebound annotations on constructors
* A way to represent immortal/static lifetimes on the C++ side

46b4983baf Concurrency: Reject nonisolated lazy properties 
We already banned nonisolated property wrappers, and 'lazy' is
conceptually similar, so it makes sense to disallow it also.

Fixes https://github.com/swiftlang/swift/issues/76513.

49aa0e966f Ensure that SourceFiles always have a backing buffer in the SourceManager 
The "buffer ID" in a SourceFile, which is used to find the source file's
contents in the SourceManager, has always been optional. However, the
effectively every SourceFile actually does have a buffer ID, and the
vast majority of accesses to this information dereference the optional
without checking.

Update the handful of call sites that provided `nullopt` as the buffer
ID to provide a proper buffer instead. These were mostly unit tests
and testing programs, with a few places that passed a never-empty
optional through to the SourceFile constructor.

Then, remove optionality from the representation and accessors. It is
now the case that every SourceFile has a buffer ID, simplying a bunch
of code.

the freestanding macro that are used under-the-hood for type checking.

02dbb96b94 AST: Rename AvailabilityContext to AvailabilityRange. 
The generality of the `AvailabilityContext` name made it seem like it
encapsulates more than it does. Really it just augments `VersionRange` with
additional set algebra operations that are useful for availability
computations. The `AvailabilityContext` name should be reserved for something
pulls together more than just a single version.
