Summary:
This documents the usage of sample profilers with Clang and the
profile format expected by LLVM's optimizers. It also documents the
profile conversion tool used by Linux Perf.

This adds Clang support for the ARM64 backend. There are definitely
still some rough edges, so please bring up any issues you see with
this patch.
As with the LLVM commit though, we think it'll be more useful for
merging with AArch64 from within the tree.

Summary:
This allows them to be used without -cc1 the same way as -I and -isystem.
Renamed the options to --system-header-prefix=/--no-system-header-prefix to avoid interference with -isystem and make the intent of the option cleaner.

This change turns -fsanitize-memory-track-origins into
-fsanitize-memory-track-origins=[level] flag (keeping the old one for
compatibility). Possible levels are 0 (off), 1 (default) and 2 (incredibly
detailed). See docs (part of this patch) for more info.

This name, while more verbose, plays more nicely with tools that use
file extensions to determine file types. The existing spelling
'module.map' will continue to work, but the new spelling will take
precedence.
In frameworks, this new filename will only go in a new 'Modules'
sub-directory.
Similarly, add a module.private.modulemap corresponding to
module_private.map.

r203272 enables generation of a Qt Compressed Help file for the LLVM source
code.
As a consequence, this change brings the same capabilities to Clang while
reusing these two variables:
LLVM_ENABLE_DOXYGEN_QT_HELP
LLVM_DOXYGEN_QHELPGENERATOR_PATH
and adding
CLANG_DOXYGEN_QCH_FILENAME="org.llvm.clang.qch"
CLANG_DOXYGEN_QHP_NAMESPACE="org.llvm.clang"
CLANG_DOXYGEN_QHP_CUST_FILTER_NAME="Clang ${CLANG_VERSION}"
CLANG_DOXYGEN_QHP_CUST_FILTER_ATTRS="Clang,${CLANG_VERSION}"

Summary:
Add loc() to the dynamic registry.
Other fixes:
- Fix the polymorphic variant value to accept an exact match, even if
there are other possible conversions.
- Fix specifiesTypeLoc() to not crash on an empty
NestedNameSpecifierLoc.

it, importers of B should not see the macro. This is complicated by the fact
that A's macro could also be visible through a different path. The rules (as
hashed out on cfe-commits) are included as a documentation update in this
change.
With this, the number of regressions in libc++'s testsuite when modules are
enabled drops from 47 to 7. Those remaining 7 are also macro-related, and are
due to remaining bugs in this change (in particular, the handling of submodules
is imperfect).

This documents some of the status of supported functionality in MSVC
quirks mode. Some of this should be in
http://clang.llvm.org/compatibility.html instead when things have
stabilized.

A 'remark' is information that is not an error or a warning, but rather some
additional information provided to the user. In contrast to a 'note' a 'remark'
is an independent diagnostic, whereas a 'note' always depends on another
diagnostic.
A typical use case for remark nodes is information provided to the user, e.g.
information provided by the vectorizer about loops that have been vectorized.
This patch provides the initial implementation of 'remarks'. It includes the
actual definiton of the remark nodes, their printing as well as basic parameter
handling. We are reusing the existing diagnostic parameters which means a remark
can be enabled with normal '-Wdiagnostic-name' flags and can be upgraded to
an error using '-Werror=diagnostic-name'. '-Werror' alone does not upgrade
remarks.
This patch is by intention minimal in terms of parameter handling. More
experience and more discussions will most likely lead to further enhancements
in the parameter handling.

Before this patch we would only use the fist occurance of a matcher
function in the documentation, for example leaving out
hasType(Matcher<QualType>).

Now that the integrated assembler is considered a first class feature of the

encourage users to switch to the feature flags.

This is a temporary stop-gap solution until server-side generation is implemented, at which point the AttributeReference.rst will go back to holding placeholder text.
