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

Summary:
The current LowerInvoke pass cannot handle invoke instructions with a
funclet bundle operand. The order of operands for an invoke instruction
is {call arguments, callee, funclet operand (if any), normal dest,
unwind dest}. The current code assumes there is no funclet operand and
incorrectly includes a funclet operand into call arguments.

Don't hardcode objcopy and strip names, rather use CMAKE_OBJCOPY and
CMAKE_STRIP variables which allows users to override the tools used
such as using llvm-objcopy and llvm-strip instead of binutils versions.

Summary:
When out-of-memory or timeout occurs, threads can be stopped during
symbolization, thereby causing a deadlock when the OOM/TO handlers
attempt symbolization. We avoid this deadlock by skipping symbolization
if another thread is symbolizing.

We enter MergeBlockIntoPredecessor with a block looking like this:
for.inc.us-lcssa: ; preds = %cond.end
%k.1.lcssa.ph = phi i32 [ %conv15, %cond.end ]
%t.3.lcssa.ph = phi i32 [ %k.1.lcssa.ph, %cond.end ]
br label %for.inc, !dbg !66
[note the first arg of the PHI being a PHI].
FoldSingleEntryPHINodes gets rid of both PHIs (calling, eraseFromParent).
But right before we call the function, we push into IncomingValues the
only argument of the PHIs, and shortly after we try to iterate over
something which has been invalidated before :(
The fix its not trying to remove PHIs which have an incoming value
coming from the same BB we're looking at.

That broke every single .clang-tidy config out there
which happened to specify AnalyzeTemporaryDtors option:
YAML:5:24: error: unknown key 'AnalyzeTemporaryDtors'
AnalyzeTemporaryDtors: false
^~~~~
Error parsing <...>/.clang-tidy: Invalid argument
More so, that error isn't actually a error, the
clang-tidy does not exit with $? != 0, it continues
with the default config.
Surely this breakage isn't the intended behavior.
But if it is, feel free to revert this commit.

Refactoring LegalizerHelper::widenScalar member function reducing its
size by approximately a factor of 2 and (hopefuly) making it more
straightforward and regular by introducing widenScalarSrc and
widenScalarDst helper methods.
The new widenScalar* methods mutate the instructions in place instead
of recreating them from scratch and removing the originals. The
compile time implications of this were measured on sqlite3
amalgamation, targeting AArch64 in -O0:
LegalizerHelper::widenScalar: > 25% faster
Legalizer::runOnMachineFunction: ~ 4.0 - 4.5% faster
Also adding MachineOperand::setCImm and refactoring out
MachineIRBuilder::recordInsertion methods to make the change possible.

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.

Before SVN r244158, codeview debug info was emitted always
emitted for msvc if debug info was enabled, but that commit
added a module flag.
Since it's still restricted by the flag, we can allow it
for any target if the user requests it, not only msvc (and
windows-itanium, added in SVN r287567).
Add a test for emitting it for a mingw target.

-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. :)

Summary:
Don't skip functions with the same name but from different files.
That change makes it possible to generate code coverage reports from
different binaries compiled from different sources even if there are functions
with non-unique names. Without that change, code coverage for such functions is
missing except of the first function processed.
