From feedback, replace the name `_debugDescription`, which was confusing because of the
underscore, with `lldbDescription`. This new name also indicates that this property may
contain [LLDB Summary Strings](https://lldb.llvm.org/use/variable.html#summary-strings).
* [stdlib] Remove docs from default implementations
Customized docs were not removed:
public static var isSigned: Bool
public static var max: Self
public static var min: Self
public var description: String
public var magnitude: Self
public init<T: BinaryInteger>(_ source: T)
public func distance(to other: Self) -> Int
public func advanced(by n: Int) -> Self
* [stdlib] Remove unused docs for "unsafe" methods
* [stdlib] Remove inherited "ReportingOverflow" docs
* [stdlib] Remove inherited docs for operators
Customized docs were not removed.
(`+`, `-`, `*`, `+=`, `-=`, `*=`)
Non-inherited docs were not removed.
(`&+`, `&-`, `&+=`, `&-=`, `&*=`)
* [stdlib] Reattach doc comments to their APIs
Use `rstrip()` to remove the trailing newline.

* [stdlib] Remove inherited docs from integer types
* [stdlib] Remove FIXME(ABI) comments
* [stdlib] Remove unused docs for operators
* [stdlib] Update example code for `-=` and `*=`
* [stdlib] Update internal gyb comments
* [stdlib] Move docs to BinaryInteger overrides
* [stdlib] Remove unused gyb code
* [stdlib] Fix `&-` and `&*` examples
- when compiling embedded cross compile target standard libraries, include AVR
- add 16-bit pointer as a conditional compilation condition and get the void pointer size right for gyb sources
- attempt to fix clang importer not importing __swift_intptr_t correctly on 16 bit platforms
- changed the unit test target to avr-none-none-elf to match the cmake build
[AVR] got the standard library compiling in a somewhat restricted form:
General
- updated the Embedded Runtime
- tweaked CTypes.swift to fix clang import on 16 bit platforms
Strings
- as discussed in https://forums.swift.org/t/stringguts-stringobject-internals-how-to-layout-on-16-bit-platforms/73130, I went for just using the same basic layout in 16 bit as 32 bit but with 16 bit pointers/ints... the conversation is ongoing, I think something more efficient is possible but at least this compiles and will probably work (inefficiently)
Unicode
- the huge arrays of unicode stuff in UnicodeStubs would not compile, so I skipped it for AVR for now.
Synchronization
- disabled building the Synchronization library on AVR for now. It's arguable if it adds value on this platform anyway.
When initializing a range set with a group of overlapping, identical,
or empty ranges, the initializer can exhibit poor performance due
to removing the unneeded ranges during processing. This change uses
a partitioning scheme instead, only removing the unnecessary ranges
at the end of initialization.
It should no longer be necessary to provide an `@_alwaysEmitIntoClient` version
of `_diagnoseUnavailableCodeReached()`. This workaround was originally added to
provide compatibility with projects that were misconfigured to compile against
a newer stdlib but link against an older one.
Resolves rdar://119892482.
The stdlib is always built with NoncopyableGenerics enabled, so `#if
$NoncopyableGenerics` guards in non-inlinable code are superfluous.
Additionally, the stdlib's interface no longer needs to support compilers
without the feature, so the guards in inlinable code can also be removed.
https://github.com/swiftlang/swift/pull/72612 can be reverted because it is no
longer necessary for the interface of the stdlib to be compatible with
compilers without `$TypedThrows` support.
