This leaves the nodes from the middle step dangling.
Guard against this by pre-checking that the number of elements is

Add -fgnuc-version= to control __GNUC__ and other GCC macros
I noticed that compiling on Windows with -fno-ms-compatibility had the
side effect of defining __GNUC__, along with __GNUG__, __GXX_RTTI__, and
a number of other macros for GCC compatibility. This is undesirable and
causes Chromium to do things like mix __attribute__ and __declspec,
which doesn't work. We should have a positive language option to enable
GCC compatibility features so that we can experiment with
-fno-ms-compatibility on Windows. This change adds -fgnuc-version= to be
that option.
My issue aside, users have, for a long time, reported that __GNUC__
doesn't match their expectations in one way or another. We have
encouraged users to migrate code away from this macro, but new code
continues to be written assuming a GCC-only environment. There's really
nothing we can do to stop that. By adding this flag, we can allow them
to choose their own adventure with __GNUC__.
This overlaps a bit with the "GNUMode" language option from -std=gnu*.
The gnu language mode tends to enable non-conforming behaviors that we'd
rather not enable by default, but the we want to set things like
__GXX_RTTI__ by default, so I've kept these separate.

```

This is because `m_operation_thread` and `m_monitor_thread` were wrapped

To fix the crashes, use `llvm::Optional<>` for the members (as indicated

`LaunchThread` and `StartMonitoringChildProcess`. Then, only assign to
the member variables after checking if the return values indicated

[PDB] Fix bug when using multiple PCH header objects with the same name.
A common pattern in Windows is to have all your precompiled headers
use an object named stdafx.obj. If you've got a project with many
different static libs, you might use a separate PCH for each one of
these.
During the final link step, a file from A might reference the PCH
object from A, but it will have the same name (stdafx.obj) as any
other PCH from another project. The only difference will be the
path. For example, A might be A/stdafx.obj while B is B/stdafx.obj.
The existing algorithm checks only the filename that was passed on
the command line (or stored in archive), but this is insufficient in
the case where relative paths are used, because depending on the
command line object file / library order, it might find the wrong
PCH object first resulting in a signature mismatch.
The fix here is to simply check whether the absolute path of the
PCH object (which is stored in the input obj file for the file that
references the PCH) *ends with* the full relative path of whatever
is specified on the command line (or is in the archive).

ADT: Save a word in every StringSet entry
Add a specialization to StringMap (actually StringMapEntry) for a
value type of NoneType (the type of llvm::None), and use it for
StringSet. This'll save us a word from every entry in a StringSet,
used for alignment with the size_t that stores the string length.
I could have gone all the way to some kind of empty base class
optimization, but that seemed like overkill. Someone can consider
adding that in the future, though.

If we've disable zmm registers, the v16i32 will need to be split. This split will propagate through min/max the truncate. This creates two sequences that need to be concatenated back to v16i8. We can instead use packusdw to do part of the clamping, truncating, and concatenating all at once. Then we can use a vpmovuswb to finish off the clamp.

update TestRunCommandInterpreterAPI to use SBFile
Summary:
If you look at what this test is doing, it's actually quite
mysterious why it works at all. It sets the input file
inside a "with open". As soon as the with block ends,
that file will be closed. And yet somehow LLDB reads
commands from it anyway. What's actually happening is that
the file descriptor gets dup'd when something inside LLDB
calls File::GetStream(). I think it's fair to say that
what this test is doing is illegal and it has no right
to expect it to work.
This patch updates the test with two cases. One uses
the SBFile api, and actually transfers ownership of
the original file descriptor to the debugger. The other
just uses the old FILE* API, but in a sane way.
I also set NO_DEBUG_INFO_TESTCASE, because this test doesn't
use any debug info and doesn't need to run three times.

win: Move Parallel.h off concrt to cross-platform code

<thread> had issues in MSVC2013, but r296906 suggests they've been fixed
