These changes caused a number of issues:
1. No debug info is emitted when a release-debug info compiler is built.
2. OS X deployment target specification is broken.
3. Swift options were broken without any attempt any recreating that
functionality. The specific option in question is --force-optimized-typechecker.
Such refactorings should be done in a fashion that does not break existing
users and use cases.

This patch splits add_swift_library into two functions one which handles
the simple case of adding a library that is part of the compiler being
built and the second handling the more complicated case of "target"
libraries, which may need to build for one or more targets.
The new add_swift_library is built using llvm_add_library, which re-uses
LLVM's CMake modules. In adapting to use LLVM's modules some of
add_swift_library's named parameters have been removed and
LINK_LIBRARIES has changed to LINK_LIBS, and LLVM_LINK_COMPONENTS
changed to LINK_COMPONENTS.
This patch also cleans up libswiftBasic's handling of UUID library and
headers, and how it interfaces with gyb sources.
add_swift_library also no longer has the FILE_DEPENDS parameter, which
doesn't matter because llvm_add_library's DEPENDS parameter has the same
behavior.
Remove 16 concrete init(stringInterpolationSegment:) overloads and
replace them with 3 generic overloads, significantly reducing the
exponential blow-up from larger string interpolations.
Fixes rdar://problem/29389887.
The old method of constructing a mangled class name does not work anymore with the new mangling scheme.
Also, by using the re-mangler, _typeByName now works with class names containing non-ascii characters.
These were overlooked, and somehow code that attempted to make a minimal collection conform to RangeReplaceableCollection and RandomAccessCollection managed to compile successfully in Swift 3.0, but in Swift 3.1…*something* changed to reject a type that conforms to both due to the lack of a suitable default slicing subscript implementation in the stdlib that provided all the requirements. Fill in these missing implementations, fixing rdar://problem/30228957.

Although it’s called via _slowPath the compiler sometimes inlines it, because it considers it to be a trivial function.
This change gives small code size improvements for benchmarks which deal with arrays.

The compiler changes introduced in
0c294314d0 now prohibit the transparent
initializer assigning to self. One such initializer was in the new
integer protocols, that made it to the master before Swift 3. Luckily it
is not used and can be safely removed for now.
In max() method’s documentation comment, The explanation says “This
example finds the smallest value in an array of height measurements.”
But, it should be “the largest value”. This commit fixes this
documentation error.
This optimization checks to see if a Character can fit in the 63-bit
small representation instead of unconditionally constructing a String
and paying the cost of that allocation. If it does, the small
representation is computed directly from its UTF-8 code units.
In optimized builds, this turns Character literals <= 8 UTF-8 code units
long into single 64-bit integer loads -- a huge improvement.
- CYGWIN symbol is used to distinguish Cygwin environment from other OS
and other environment in Windows.
- Added windows and windowsCygnus to OSVersion in StdlibUnittest
Added documentation description for third parameter of
formIndex(_:offsetBy:limitedBy:)
which was previously omitted.
Description copied from the 'index(_:offsetBy:limitedBy:)' method.
This commit adds a fix-it to remove @discardableResult on functions that return Void or Never. The fix-it is at the warning level. A test was added to verify that the fix-it removes the @discardableResult. This issue was reported in SR-3359:
https://bugs.swift.org/browse/SR-3359
Changes:
TypeCheckAttr.cpp: implemented AttributeChecker::visitDiscardableResultAttr to add a fix-it to remove @discardableResult on functions returning Void or Never.
DiagnosticsSema.def: Added a warning with a diagnostic message.
LoggingWrappers.swift.gyb, HashedCollections.swift.gyb: Removed @discardableResult on functions returning Void.
fixits-apply-all.swift, fixits-apply-all.swift.result: Added tests to verify that @discardableResult is removed from functions returning Void or Never.
* Removing uses of mixed-type + and - in benchmarks
Using type cast or explicit type annotations.
* Deprecating use of + and - on SignedInteger
As it leads to mixed type arithmetics that is not supposed to work.
It was needed before the new collection indexing model to make moving
indexes simple.
* Test deprecation warning
If you don't have PkgConfig, you'll need to pass the following to CMake:
```
-DICU_UC_INCLUDE_DIRS="%swift_source_dir%/icu/include"^
-DICU_UC_LIBRARY_DIRS="%swift_source_dir%/icu/lib64"^
-DICU_I18N_INCLUDE_DIRS="%swift_source_dir%/icu/include"^
-DICU_I18N_LIBRARY_DIRS="%swift_source_dir%/icu/lib64"^
-DICU_UC_LIB_NAME="icuuc"^
-DICU_I18N_LIB_NAME="icuin"
```

Piggybacks some resilience diagnostics onto the availability
checking code.
Public and versioned functions with inlineable bodies can only
reference other public and internal entities, since the SIL code
for the function body is serialized and stored as part of the
module.
This includes @_transparent functions, @_inlineable functions,
accessors for @_inlineable storage, @inline(__always) functions,
and in Swift 4 mode, default argument expressions.
The new checks are a source-breaking change, however we don't
guarantee source compatibility for underscored attributes.
The new ABI and tests for the default argument model will come in
subsequent commits.
