This is similar to the LLVM change https://reviews.llvm.org/D46290.
We've been running doxygen with the autobrief option for a couple of
years now. This makes the \brief markers into our comments
redundant. Since they are a visual distraction and we don't want to
encourage more \brief markers in new code either, this patch removes
them all.

This doesn't make any difference since we don't use RPATH/RUNPATH
on Fuchsia but it avoids the CMake error when re-linking libraries
while building with Ninja.

As Eli brought up here: https://reviews.llvm.org/D46535
I'd previously messed up this fix by missing conversions
that are just slightly outside the range. This patch fixes
this by no longer ignoring the return value of
convertToInteger. Additionally, one of the error messages
wasn't very sensical (mentioning out of range value, when it
really was not), so it was cleaned up as well.

Since we're working on turning the MachineOutliner by default under -Oz for
AArch64, it makes sense to have an -mno-outline flag available. This currently
doesn't do much (it basically just undoes -moutline).
When the MachineOutliner is on by default under AArch64, this flag should
set -mllvm -enable-machine-outliner=never.

-dwarf-column-info is omitted if -gcodeview is specified for msvc
targets at the moment, but since -gcodeview is an option that can be
specified for any target, there's little reason to restrict this
handling to msvc targets.
This allows getting proper codeview debug info by passing -gcodeview
for e.g. MinGW targets as well.

Nitpicky, but the MachineOutliner is a machine-level pass, and so we should
reflect that by using "m" instead of "n".
Figured we should get this in before people get used to the letter f. :)

This patch addresses some mostly trivial post-commit review comments received
on r331677.
Additionally, this patch fixes an assertion in `getNarrowingKind` caused by
the use of an uninitialized value from `checkThreeWayNarrowingConversion`.

In order to match our mangling scheme, use a different set of numbers for
decomposition declarations, and consider all binding names when forming the
numbering. This does not yet affect any mangled names we produce, because
local decomposition declarations can't yet have linkage, but a C++ standard
proposal to change that is currently being processed.

Without this we throw an error on the header file instead of the user code when the right features aren't enabled in clang.
Rename the other DEFAULT_FN_ATTRS defines to _Z for 512-bit since I used _Y for this case.

Summary:
This patch tackles long hanging fruit for the builtin operator<=> expressions. It is currently needs some cleanup before landing, but I want to get some initial feedback.
The main changes are:
* Lookup, build, and store the required standard library types and expressions in `ASTContext`. By storing them in ASTContext we don't need to store (and duplicate) the required expressions in the BinaryOperator AST nodes.
* Implement [expr.spaceship] checking, including diagnosing narrowing conversions.
* Implement `ExprConstant` for builtin spaceship operators.
* Implement builitin operator<=> support in `CodeGenAgg`. Initially I emitted the required comparisons using `ScalarExprEmitter::VisitBinaryOperator`, but this caused the operand expressions to be emitted once for every required cmp.
* Implement [builtin.over] with modifications to support the intent of P0946R0. See the note on `BuiltinOperatorOverloadBuilder::addThreeWayArithmeticOverloads` for more information about the workaround.

Currently LLVM CFI tries to use an implicit blacklist file, currently
in /usr/lib64/clang/<version>/share. If the file is not there, LLVM
happily continues, which causes CFI to add checks to files/functions
that are known to fail, generating binaries that fail. This CL causes
LLVM to die (I hope) if it can't find these implicit blacklist files.

As identified and briefly discussed here:
https://bugs.llvm.org/show_bug.cgi?id=37305
Converting a floating point number to an integer type when
the integral part is out of the range of the integer type is
undefined behavior in C. Additionally, CodeGen emits an undef
in this situation.
HOWEVER, we've been giving a warning that says that the value is
changed. This patch corrects the warning to list that it is actually
undefined behavior.

I found that explicit template parameters that caused a
narrowing integer conversion resulted in the incorrect parameter
being mentioned in the note (see test attached). This is because
the argument checking code doesn't check to see if it caused
SFINAE errors when checking the arguments, so instead of giving
up on the first error, it continues through the list. This
makes the error reporting pick up the last template param every time.
This patch checks these parameters on each argument and gives up
if there is an error. The result is that only the required amount
of arguments are checked, and that the 'Converted' array contains
only the successful arguments before the first failure, as the
calls seem to all expect.

In order to disable PIC and to match GCC behaviour, -mno-abicalls
option is neccessary. When -fno-[pic/PIC] is used witout -mno-abicalls,
warning is reported. An error is reported when -fno-pic or -fno-PIC is
used in combination with -mabicalls.
In this commit, test case is added.
Depends on D44381.

This implements the rule intended by the standard (see LWG 2358)
and the rule intended by the Itanium C++ ABI (see
https://github.com/itanium-cxx-abi/cxx-abi/pull/51), and makes
Clang match the behavior of GCC, ICC, and MSVC.
A pedantic reading of both the standard and the ABI indicate that Clang
is currently technically correct, but that's not worth much when it's
clear that the wording is wrong in both those places.
This is an ABI break for classes that derive from a class that is empty
other than one or more unnamed non-zero-length bit-fields. Such cases
are expected to be rare, but -fclang-abi-compat=6 restores the old
behavior just in case.

The error turns out to be:
Assertion failed: (Target.isCompatibleDataLayout(getDataLayout()) && "Can't create a MachineFunction using a Module with a " "Target-incompatible DataLayout attached\n"), function init, file /Users/buildslave/jenkins/workspace/clang-stage1-cmake-RA-incremental/llvm/lib/CodeGen/MachineFunction.cpp, line 180.
Add -target to address this. Also re-enable the test I had temporarily
commented, and move it further down in case there is still a failure
(since it pipes stderr to FileCheck).
