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.
