Upgrade instructions:
$ mv llvm/include/llvm/Config/config.h ./config.h.BACKUP
# copy the configure line from line 7 of llvm/config.log
# (for example: `$ ./configure --no-create --no-recursion`)
$ mkdir build
$ cd build
# run the configure line, but this time with '../llvm' at the beginning:
$ ../llvm/configure --no-create --no-recursion
These warnings will soon be turned into hard errors after a week. Speak up now
if this is going to be a problem for you.

These tests link against host lldb API. Compiler's target triple
must match liblldb triple. Instead of naively skipping i386, I added
a check of the liblldb arch against the compiler target arch.
This is useful for 32 bit API builds (planned for Windows)
Since remote is disabled, we can assume the os is the same.
Also, removed skipIfLinuxClang because it's passing

In the lnt benchmark MultiSource/Benchmarks/MallocBench/gs/gs with
scalar and PHI modeling we detected the multidimensional accesses
with sizes variant in the SCoP. This will check the sizes for validity.

This change adds location information for the detected regions in Polly when the
required debug information is available.
The JSCOP output format is extended with a "location" field which contains the
information in the format "source.c:start-end"
The dot output is extended to contain the location information for each nested
region in the analyzed function.
As part of this change, the existing getDebugLocation function has been moved
into lib/Support/ScopLocation.cpp to avoid having to include
polly/ScopDetectionDiagnostics.h.

Using GetNumBytesInBuffer() assumes that the stream was not flushed between
the GetNumBytesInBuffer() calls, which may happen to be true or not,
depending on stream policy. tell() always reports the correct stream location.
Do note there are only two more uses of GetNumBytesInBuffer() in LLVM+clang, in
lib/MC/MCAsmStreamer.cpp and lib/Target/R600/InstPrinter/AMDGPUInstPrinter.cpp.
The former may be replacable by tell (needs testing) but while the later can
not be immediatly replaced by tell() as it uses the absolute value of
GetNumBytesInBuffer() rather than the real stream position. Both uses seems
to depend upon flush policy and thus may not work correctly depending upon the
stream behaviour.
Going forward, GetNumBytesInBuffer() should probably be protected, non-accessible
to raw_ostream clients.

Removed code that was replicating v8i16 'shift + mask' implementation that is done more nicely by making use of LowerScalarImmediateShift

OriginalColumn might not be set, so fall back to Location and SourceMgr
in case it is missing. Also initialize end column in case the token is
multi line, but it's the ` token itself that starts the multi line.

Parameters can have templated types and default values (= ...), which is
another location in which a template closer should be followed by
whitespace.

This test verifies that we can detect when the inheritance paths are
ambiguous due to covariant thunks, ensuring we don't regress PR16759.

The fact that PGO has a say in how these branch weights are determined
isn't interesting to most of CodeGen, so it makes more sense for this
API to be accessible via CodeGenFunction rather than CodeGenPGO.

The underlying problem is that there is currently no way to run
ObjCARCContract from llvm bitcode which is required by ObjC ARC.
This fix the problem by always enable ObjCARCContract pass if
optimization is enabled. The ObjCARC Contract pass has almost no
overhead on code that is not using ARC.

No functional change. This just makes it more obvious that the logic
in ComputeRegionCounts only depends on the counter map and local
state.

Summary:
r235916 marked only one of the tests as xfail, but the other also has
been failing intermitantly on the buildbot.

This removes the RegionCounter class, which is only used as a helper
in teh ComputeRegionCounts stmt visitor. This class is just an extra
layer of abstraction that makes the code harder to follow at this
point, and removing it makes the logic quite a bit more direct.

follow-up to the change in r235158. Right now if you attach to
a process and type "kill", lldb doesn't kill it, it detaches.

The MSVC ABI has a bug introduced by appending to the end of vftables
which come from virtual bases: covariant thunks introduces via
non-overlapping regions of the inheritance lattice both append to the
same slot in the vftable.
It is possible to generate correct vftables in cases where one node in
the lattice completely dominates the other on the way to the base with
the vfptr; in all other cases, we must raise a diagnostic in order to
prevent the illusion that we succeeded in laying out the vftable.
This fixes PR16759.

A class might contain multiple ways of getting to a vbase, some of which
are virtual and other non-virtual. It may be the case that a
non-virtual base contains an override of a method in a vbase. This
means that we must carefully pick between a set of nvbases to determine
which is the best.
As a consequence, the findPathForVPtr algorithm is considerably simpler.

This flag specifies that the normal visibility rules should be used even for
local submodules (submodules of the currently-being-built module). Thus names
will only be visible if a header / module that declares them has actually been
included / imported, and not merely because a submodule that happened to be
built earlier declared those names. This also removes the need to modularize
bottom-up: textually-included headers will be included into every submodule
that includes them, since their include guards will not leak between modules.
So far, this only governs visibility of macros, not of declarations, so is not
ready for real use yet.

Cyclone actually supports all the goodies you'd expect to come with an AArch64
CPU, so it doesn't need its own clause. Also we should probably be testing
these clauses.

The LHS was already being corrected before being set to ExprError when
the RHS is invalid, but when it was present the middle of a ternary
expression would be dropped in the error paths.
Fixes PR23350.
