I couldn't find any documentation that this form existed either. Nor is there documentation for one of the remaining two forms, but there is a testcase that uses it.

would come from changing the type of ASTContext::DeclAttrs from
DenseMap<Decl*,AttrVec*> to DenseMap<Decl*,AttrVec>), and it turns out to be
impractical to avoid the allocation there, because we expose the address of the
attribute vector in ways that are hard to fix.

As The default CMAKE install prefix is /usr/local ( https://cmake.org/cmake/help/v3.0/variable/CMAKE_INSTALL_PREFIX.html ),
sudo ninja install ends up installing clang, LLVM and libcxx under /usr/local.
In development scenario, when clang is run from the build location it will not
find libcxx at neither (build location)/../include/c++ nor /usr/include/c++.
This patch lets development clang find system installed libcxx without adding
-isystem /usr/local/include/c++. Also addresses the FIXME by explaining the
use-case for these include paths.

In Chrome, this would have found two true positives around CreateThread
if we hadn't already fixed them while rolling out ASan. We didn't get
any other hits in Chrome. I'm curious to hear if this warning finds
anything in other projects.

When remapped files were changed, they would not always cause the preamble's PCH to be invalidated, because the remapped path didn't necessarily match the include path (e.g. slash direction -- this happens a lot on Windows). I fixed this by moving to a llvm::sys::fs::UniqueID-based map instead of comparing paths stringwise.

For better performance and to unify code with offloading part we pass
scalar firstprivate values by value, instead of by reference. It will
remove some extra copying operations.

Summary:
Simply looking at the final text greatly simplifies the algorithm and also
fixes a reported issue. This requires duplicating the "actual encoding width"
logic, but that seems cleaner than the column acrobatics before.

This is a mostly mechanical change accomplished with a script. I tried to split out any changes to the typecasts that already existed into separate commits.

If we are processing a #include from a module build, we should treat it
as a system header if we're building a system module. Passing an optional
flag to HeaderSearch::LookupFile.
Before this, the testing case will crash when accessing a freed FileEntry.

Added doxygen comments to avxintrin.h's intrinsics. As of now, only around 50% of the intrinsics in this file are documented here. The patches for the other half will be sent out later.
Updated bmiintrin.h to fix an incorrect section name.
Updated f16cintrin.h to fix incorect parameter names.
The doxygen comments are automatically generated based on Sony's intrinsics document.
I got an OK from Eric Christopher to commit doxygen comments without prior code
review upstream.

Also added named casts and propagation of "implicit" to fix the LLDB testsuite.
This is a fixed commit of r269546, which was reverted by r269575.
Thanks to Aleksei Sidorin for review and advice.

getModuleContainingLocation ends up on the hot-path for typical C code
which can lead to calls to getFileIDSlow.
To speed this up, short circuit inferModuleFromLocation when there
aren't any modules, implicit or otherwise.
This shaves 4-5% build time when building the linux kernel.

Embedded bitcode should have private linkage instead of appending or external.
Otherwise, it will cause link failure due to duplicated symbols.
Also add llvm.embedded.module and llvm.cmdline to llvm.compiler.used so they
don't get optimized out.

Visual Studio's C++ standard library headers include intrin.h, so the intrinsic
headers get included a lot more often in Microsoft mode than elsewhere. The
AVX512 intrinsics are a lot of code (0.7 MB, causing 30% compile time overhead
for small programs including e.g. <string> and 6% compile time overhead for
larger projects like e.g. v8). Since multiversioning can't be relied on in
Microsoft mode (cl.exe doesn't support it), having faster compiles seems like
the much better tradeoff until we have a better intrinsic story going forward
(which we'll need for e.g. PR19898).
Actually using intrinsics on Windows already requires the right /arch:
settings, so this patch should have no big behavior change.
See also thread "The intrinsics headers (especially avx512) are too big. What
to do about it?" on cfe-dev.
