Reset of the release notes after the branching of 3.5

[rengolin]

Looks good, but you should get an ack from Sean.

We should make this change after the release. Traditionally Bill has merged the in-tree release notes into the release branch at some late point in the release cycle. The reason is that it is easier for developers to modify the in-tree version than the one on the release branch.

-What's New in Clang 3.5?
+What's New in Clang 3.6?
 ========================
 
 Some of the major new features and improvements to Clang are listed

 Major New Features
 ------------------
 
-- Clang uses the new MingW ABI
-  GCC 4.7 changed the mingw ABI. Clang 3.4 and older use the GCC 4.6
-  ABI. Clang 3.5 and newer use the GCC 4.7 abi.
 
-- The __has_attribute feature test is now target-aware. Older versions of Clang
-  would return true when the attribute spelling was known, regardless of whether
-  the attribute was available to the specific target. Clang now returns true
-  only when the attribute pertains to the current compilation target.

 Improvements to Clang's diagnostics
 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
 
 Clang's diagnostics are constantly being improved to catch more issues,
 explain them more clearly, and provide more accurate source information
-about them. The improvements since the 3.4 release include:
+about them. The improvements since the 3.5 release include:
 
-- GCC compatibility: Clang displays a warning on unsupported gcc
-  optimization flags instead of an error.

 New Compiler Flags
 ------------------
 
-The integrated assembler is now turned on by default on ARM (and Thumb),
-so the use of the option `-fintegrated-as` is now redundant on those
-architectures. This is an important move to both *eat our own dog food*
-and to ease cross-compilation tremendously.
-
-We are aware of the problems that this may cause for code bases that
-rely on specific GNU syntax or extensions, and we're working towards
-getting them all fixed. Please, report bugs or feature requests if
-you find anything. In the meantime, use `-fno-integrated-as` to revert
-back the call to GNU assembler.
-
-In order to provide better diagnostics, the integrated assembler validates
-inline assembly when the integrated assembler is enabled.  Because this is
-considered a feature of the compiler, it is controlled via the `fintegrated-as`
-and `fno-integrated-as` flags which enable and disable the integrated assembler
-respectively.  `-integrated-as` and `-no-integrated-as` are now considered
-legacy flags (but are available as an alias to prevent breaking existing users),
-and users are encouraged to switch to the equivalent new feature flag.
-
-Deprecated flags `-faddress-sanitizer`, `-fthread-sanitizer`,
-`-fcatch-undefined-behavior` and `-fbounds-checking` were removed in favor of
-`-fsanitize=` family of flags.
-
-It is now possible to get optimization reports from the major transformation
-passes via three new flags: `-Rpass`, `-Rpass-missed` and `-Rpass-analysis`.
-These flags take a POSIX regular expression which indicates the name
-of the pass (or passes) that should emit optimization remarks.
-
-The option `-u` is forwarded to the linker on gnutools toolchains.
-
 New Pragmas in Clang
 -----------------------
 
-Loop optimization hints can be specified using the new `#pragma clang loop`
-directive just prior to the desired loop. The directive allows vectorization,
-interleaving, and unrolling to be enabled or disabled. Vector width as well
-as interleave and unrolling count can be manually specified.  See language
-extensions for details.
-
-Clang now supports the `#pragma unroll` and `#pragma nounroll` directives to
-specify loop unrolling optimization hints.  Placed just prior to the desired
-loop, `#pragma unroll` directs the loop unroller to attempt to fully unroll the
-loop.  The pragma may also be specified with a positive integer parameter
-indicating the desired unroll count: `#pragma unroll _value_`.  The unroll count
-parameter can be optionally enclosed in parentheses. The directive `#pragma
-nounroll` indicates that the loop should not be unrolled.

 C Language Changes in Clang

 Internal API Changes

 Clang. If upgrading an external codebase that uses Clang as a library,
 this section should help get you past the largest hurdles of upgrading.
 

 Static Analyzer
 ---------------
 
-The `-analyzer-config` options are now passed from scan-build through to
-ccc-analyzer and then to Clang.
-
-With the option `-analyzer-config stable-report-filename=true`,
-instead of `report-XXXXXX.html`, scan-build/clang analyzer generate
-`report-<filename>-<function, method name>-<function position>-<id>.html`.
-(id = i++ for several issues found in the same function/method).
-
-List the function/method name in the index page of scan-build.
