These APIs are from the Swift 1.2 => Swift 2.0 transition, and are not
relevant anymore.
Removing them reduces the surface area of the library that needs to be
reviewed.
This reflects the fact that the attribute's only for compiler-internal use, and isn't really equivalent to C's asm attribute, since it doesn't change the calling convention to be C-compatible.
Swift was failing to autolink frameworks in the new text-based SDKs.
Clang r253060 fixes the underlying issue, so we can go back to relying
on autolinking for these.
This reverts the following commits (newest to oldest):

All refutable patterns and function parameters marked with 'var'
is now an error.
- Using explicit 'let' keyword on function parameters causes a warning.
- Don't suggest making function parameters mutable
- Remove uses in the standard library
- Update tests

This is needed after commit [2504257] DeadCodeElimination: remove dead overflow producing operations together with the cond_fail which handles the overflow.
Some of the tests had bitrotted, and others no longer worked
because they used frameworks such as CoreAudio that are not
available in the public SDK for watchOS.

This was ... returning the same thing as the == operator.
Also, integrate the CoreMedia overlay tests from
rdar://problem/20926198, which caught this problem, and port it
to StdlibUnittest.
Swift SVN r32484
Slice types that are RangeReplaceable (like ArraySlice) now slice
themselves in removeFirst(). Previously, these types were picking up
the wrong default implementation, and they were going through
replaceRange(), which caused all indices to be invalidated. The new
implementation preserves all indices.

Swift SVN r31918
Revert "Add test cases to exercise the native String vs cocoa buffer String path."
Revert "stdlib: Add back a test I removed"
Revert "stdlib: Fix hasPrefix,hasSuffix tests"
Revert "stdlib: Add documentation for the cached ascii collation tables"
This reverts commit 31493, 31492, 31491, 31490, 31489.
There are linking errors in SwiftExternalProjects (we probably have to link
against libicucore somewhere).
Swift SVN r31543
Reapply of 31474 with a fix in _compareCocoaBuffer to use the bufferSizeRhs
variable instead of bufferSizeLhs for the right hand side buffer.
We no longer create intermediate NSString copies to compare and hash swift
Strings. Instead we call directly into the ICU library.
I measured a 1.2 to 2x improvement on dictionary benchmarks as a result of this.
The SuperChars benchmark is also about 1.2x faster because of this.
Pure ASCII comparison has gotten a little bit slower (20% on a pure comparison
micro-benchmark) because we no longer do a memcmp. Doing a memcmp on ASCII is
not the same as the default unicode collation. Instead we have to a string scan.
The default unicode collation does not order like ASCII does and ignores
characters (for example the \0 character).

Revert "stdlib: Add back a test I removed"
Revert "Add test cases to exercise the native String vs cocoa buffer String path."
Revert "stdlib: Move the darwin String implementation over to use the ICU library."
This reverts commit r31477, r31476, r31475, r31474.
Commit r31474 broke the ASAN build.
