This is the first patch in the coroutine series.
It contains the documentation for the coroutine intrinsics and their usage.
Patch by Gor Nishanov!

Summary:
The llvm.invariant.start and llvm.invariant.end intrinsics currently
support specifying invariant memory objects only in the default address
space.
With this change, these intrinsics are overloaded for any adddress space
for memory objects
and we can use these llvm invariant intrinsics in non-default address
spaces.
Example: llvm.invariant.start.p1i8(i64 4, i8 addrspace(1)* %ptr)
This overloaded intrinsic is needed for representing final or invariant
memory in managed languages.

Given that other proposals are making their way through, it's better if we
specify what GitHub proposal this is, in case there are others that also
involve GitHub, but not sub-modules.

Lots of blocks had "llvm" or "nasm" syntax types but either weren't following
the syntax, or the syntax has changed (and sphinx hasn't keep up) or the type
doesn't even exist (nasm?).
Other documents had :options: what were invalid. I only removed those that had
warnings, and left the ones that didn't, in order to follow the principle of
least surprise.
This is like this for ages, but the buildbot is now failing on errors. It may
take a while to upgrade the buildbot's sphinx, if that's even possible, but
that shouldn't stop us from getting docs updates (which seem down for quite
a while).
Also, we're not losing any syntax highlight, since when it doesn't parse, it
doesn't colour. Ie. those blocks are not being highlighted anyway.
I'm trying to get all docs in one go, so that it's easy to revert later if we
do fix, or at least easy to know what's to fix.

This document was crafted from the various (320+) emails between 2nd June and
20th July regarding the move to GitHub. It tried to consolidate every issue that
was raised and every solution that was presented to have a GitHub repository
with sub-modules.
It *does not* try to argue whether sub-modules are better or worse than any other
Git solution, nor if Git is better than any other VCS, nor if GitHub is better
than any other free code hosting service. This is just the final conclusions of
48 days and 320 emails (plus a lot of IRC discussions) on the LLVM community.
This document will be presented at the survey that the foundation will setup for
us to decide if we move to this solution or not. It reflects what was discussed
on the lists, but it's not authoritative. If something is not clear enough,
please refer to the mailing list discussions (hint: search for "GitHub").

Add a "-j" option to llvm-profdata to control the number of threads used.
Auto-detect NumThreads when it isn't specified, and avoid spawning threads when
they wouldn't be beneficial.
I tested this patch using a raw profile produced by clang (147MB). Here is the
time taken to merge 4 copies together on my laptop:
No thread pool: 112.87s user 5.92s system 97% cpu 2:01.08 total
With 2 threads: 134.99s user 26.54s system 164% cpu 1:33.31 total
Changes since the initial commit:
- When handling odd-length inputs, call ThreadPool::wait() before merging the
last profile. Should fix a race/off-by-one (see r275937).

The default behavior of bugpoint is to print "<crash>" when it finds a reduced
test that crashes compilation. With this flag we now can see the output of the
crashing program. This is useful to make sure it is the same error being
tracked down and not a different error that happens to crash the compiler as
well.

Add an option to specify a symbol demangler (as well as options to the
demangler). This can be used to make reports more human-readable.
This option is especially useful in -output-dir mode, since it isn't as
easy to manually pipe reports into a demangler in this mode.

This adds Clang-specific DWARF constants for nullability and ObjC
class properties that are already generated by clang. This patch adds
dwarfdump support and a more comprehensive testcase.

The description of the 'returned' attribute says that it is only used when
code-generating the caller. I'd like to make the optimizer smarter about
looking through functions with returned arguments (generally, but motivated by
my llvm.noalias work). As David pointed out in the review of D22202, the
LangRef should be updated to make its expanded uses clearer.

Text suggested by Daniel Berlin. While it is likely to be exactly what
the advisory committee would do anyway, codifying it does no harm and
helps reassure people that rare does not mean arbitrary.

Summary:
This complements the earlier addition of IntrWriteMem and IntrWriteArgMem
LLVM intrinsic properties, see D18291.
Also start using the attribute for memset, memcpy, and memmove intrinsics,
and remove their special-casing in BasicAliasAnalysis.

This new chapter describes compiling LLVM IR to object files.
The new chaper is chapter 8, so later chapters have been renumbered.
Since this brings us to 10 chapters total, I've also needed to rename
the other chapters to use two digit numbering.

associated reporting guide.
I want to emphasize that at this point these are just drafts!
This is the result of very extended discussion on the mailing lists on
several different threads:
http://lists.llvm.org/pipermail/llvm-dev/2015-October/091218.htmlhttp://lists.llvm.org/pipermail/llvm-dev/2016-May/099120.htmlhttp://lists.llvm.org/pipermail/llvm-commits/Week-of-Mon-20151019/307070.html
The reporting guide in particular I anticipate will be shaped somewhat
by the advisory committee when they are selected. But hopefully this
serves as a good starting point and good guidance while the advisory
committee is being sorted out.
I'd like to thank all the folks who contributed to this. Many, *many*
people worked to help with drafting, wording, suggestions, and edits.
Also, this is based on widely used existing codes of coduct as mentioned
in the text, and the original authors of those deserve many thanks as
well.

This is a resubmittion of 263158 change after fixing the existing problem with intrinsics mangling (see LTO and intrinsics mangling llvm-dev thread for details).
This patch fixes the problem which occurs when loop-vectorize tries to use @llvm.masked.load/store intrinsic for a non-default addrspace pointer. It fails with "Calling a function with a bad signature!" assertion in CallInst constructor because it tries to pass a non-default addrspace pointer to the pointer argument which has default addrspace.
The fix is to add pointer type as another overloaded type to @llvm.masked.load/store intrinsics.

Passing -output-dir path/to/dir to llvm-cov show creates path/to/dir if
it doesn't already exist, and prints reports into that directory.
In function view mode, all views are written into
path/to/dir/functions.$EXTENSION. In file view mode, all views are
written into path/to/dir/coverage/$PATH.$EXTENSION.
