...to remove the temptation to put everything in one file with the same
name as the module. This doesn't do anything for overlays that /already/
have everything in one file with the same name as the module, except for
a few easy cases; we can unpack the rest later.
os/activity.h or os/log.h. Update cmake files again, hardcoding a Darwin
dependency. The script does not notice that Foundation depends on
CoreGraphics, so add that manually.
Also found that MapKit is supported on WATCHOS but we didn't have dependencies
for that.
Favor one line per supported SDK instead of catch-all dependency lines.
Distinguish from SDKs which have no dependencies vs SDKs which are
unsupported on a particular platform by printing `unsupported` to the
console and remove the line in the cmake file because it should
not exist anyway.
This full cleanup was not done before because of circularity detected by the
util, which has since been fixed.
Support directories with spaces.
Like NSObject, CFType has primitive operations CFEqual and CFHash,
so Swift should allow those types to show up in Hashable positions
(like dictionaries). The most general way to do this was to
introduce a new protocol, _CFObject, and then have the importer
automatically make all CF types conform to it.
This did require one additional change: the == implementation that
calls through to CFEqual is in a new CoreFoundation overlay, but the
conformance is in the underlying Clang module. Therefore, operator
lookup for conformances has been changed to look in the overlay for
an imported declaration (if there is one).

As a first step to allowing the build script to build *only*
static library versions of the stdlib, change `add_swift_library`
such that callers must pass in `SHARED`, `STATIC`, or `OBJECT_LIBRARY`.
Ideally, only these flags would be used to determine whether to
build shared, static, or object libraries, but that is not currently
the case -- `add_swift_library` also checks whether the library
`IS_STDLIB` before performing certain additional actions. This will be
cleaned up in a future commit.
- Removed unnecessary #if guard
- Used IOReturn instead of Int32 return type
- Avoided private access control for overlays
- Added a test to ensure the type of the constants matches the return type of a IOKit function
