Now that the integrated assembler is considered a first class feature of the
compiler and has a proper feature flag, document the change in the compiler
flags. Ensure that we indicate that the legacy flags are still available, but,
encourage users to switch to the feature flags.

This is an experimental feature, where -integrated-as will be
on by default on ARM/Thumb. We aim to detect the missing features
so that the next release is stable.
Updating the ReleaseNotes, too.
Also moving the AArch64 into the same place.

Summary:
Currently with clang:
$ clang -O20 foo.c
error: invalid value '20' in '-O20'
With the patch:
$ clang -O20 foo.c
warning: optimization level '-O20' is unsupported; using '-O3' instead.
1 warning generated.
This matches the gcc behavior (with a warning added)
Pass all tests:
Testing: 0 .. 10.. 20.. 30.. 40.. 50.. 60.. 70.. 80.. 90..
Testing Time: 94.14s
Expected Passes : 6721

Trying to fix test failures since earlier today.
One of the tests added in this commit is outputting test/Driver/clang_f_opts.s
which the builders that build in-tree (eg. clang-native-arm-cortex-a9) are
trying to run as a test case, causing failures.
clang_f_opts.c:
If -### doesn't emit the warning then this test probably shouldn't be in
here in the first place. Frontend maybe?
invalid-o-level.c:
Running %clang_cc1 in the Driver tests doesn't make sense because -cc1
bypasses the driver. (I'm not reverting the commit that introduced this but
please fix instead of keeping it this way.)
Reverting to fix the build failures and also so that the tests can be thought
out more thoroughly.
This reverts commit r194817.

limited ways) after the next release. See the lengthy discussions (which
are on-going) and the corresponding commit to LLVM's release notes.
Nothing is actually changing at this point, this is just further
spreading the plan.

A class with a field of non-POD-for-layout type is not POD-for-layout.
This computation should not depend on whether the field is of POD type
in the language sense.
Fixes PR16537.
Patch by Josh Magee.

This will enable users in security critical applications to perform
checked-arithmetic in a fast safe manner that is amenable to c.
Tests/an update to Language Extensions is included as well.

http://lab.llvm.org:8011/builders/clang-x86_64-darwin10-gdb went back green
before it processed the reverted 178663, so it could not have been the culprit.
Revert "Revert 178663."
This reverts commit 4f8a3eb2ce5d4ba422483439e20c8cbb4d953a41.

For variables and functions clang used to store two storage classes. The one
"as written" in the code and a patched one, which, for example, propagates
static to the following decls.
This apparently is from the days clang lacked linkage computation. It is now
redundant and this patch removes it.

After changing the way several value inheritance hierarchies (TypeLoc,
CFGelement, ProgramPoint and SVal) handle casting, this documentation describes
how 3rd party code may need to be updated to compile with the new APIs.
As suggested by Sean Silva on cfe-dev.

I'm using the name "Extended Identifiers" for the feature because that's
what GCC calls them. According to the standard, the new feature is
"universal character names are now allowed in identifiers", but the more
interesting "feature" is that identifiers can now contain Unicode characters,
however they are written.

Even though we do have a `.. warning::` directive on the page, hopefully
having "In-Progress" in the title will help to condition people's
expectations a bit for when they run into the extremely bare-bones
release notes.
Also, when release season comes around again, maybe this will get
people's attention and avoid confusion about what is going into the
upcoming release, and what is for changes to trunk for the next version.

This is the last of the "regular" documents to convert to reST, and so
I'm declaring the initial clang reST conversion "done".
However,
- There are some documents in clang/www/ which probably should
be migrated into clang/docs/, such as www/OpenProjects.html
The primary thing blocking me from doing this right now is not knowing
how to set up a redirect so that the old URL's continue to work.
- LibASTMatchersReference.html is not reST. This page is auto-generated
by clang/docs/tools/dump_ast_matchers.py from the source and has some
collapse/expand logic that isn't expressible directly with Sphinx, so
just converting it to reST is not really a good strategy.
Manuel Klimek and I discussed this and the general agreed-upon
direction is making that page data-driven so that it, say, pulls in an
auto-generated blob of JSON which describes the matchers and builds up
the "matcher reference" part of the page with a small amount of JS.
- There are some rogue .txt files hanging around.
Also, I dropped the little dragon logo at the top because Sphinx was
warning about an external image reference (not sure why, but meh, I
didn't want to fight it). If anything, we would want such a logo
integrated into the site's overall theme, rather than hardcoded here.
