Summary:
This new debug emission kind supports emitting line location
information in all instructions, but stops code generation
from emitting debug info to the final output.
This mode is useful when the backend wants to track source
locations during code generation, but it does not want to
produce debug info. This is currently used by optimization
remarks (-Rpass, -Rpass-missed and -Rpass-analysis).
When one of the -Rpass flags is used, the front end will enable
location tracking, only if no other debug option is enabled.
To prevent debug information from being generated, a new debug
info kind LocTrackingOnly causes DIBuilder::createCompileUnit() to
not emit the llvm.dbg.cu annotation. This blocks final code generation
from generating debug info in the back end.
Depends on D4234.

Init-order and use-after-return modes can currently be enabled
by runtime flags. use-after-scope mode is not really working at the
moment.
The only problem I see is that users won't be able to disable extra
instrumentation for init-order and use-after-scope by a top-level Clang flag.
But this instrumentation was implicitly enabled for quite a while and
we didn't hear from users hurt by it.

Summary:
Add hasLocalStorage/hasGlobalStorage matchers for VarDecl nodes.
Update the doc. Also add them to the dynamic registry.

cxx_init_captures to specify the right feature-check name.

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.

These flags are deprecated since at least Clang 3.3. Users should instead
use -fsanitize= with appropriate values.

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.
