Update the Visual Studio Integration from user feedback.
This patch removes the MSBuild warnings about options that
clang-cl ignores. It also adds several additional fields to
the LLVM Configuration options page. The first is that it
adds support for LLD! To give the user flexibility though,
we don't want to force LLD to always-on, and if we're not
forcing LLD then we might as well not force clang-cl either.
So we add options that can enable or disable lld, clang-cl,
or any combination of the two. Whenever one is disabled,
it falls back to the Microsoft equivalent.
Additionally, for each of clang-cl and lld-link, we add a new
configuration setting that allows Additional Options to be
passed for that specific tool only. This is similar to the
C/C++ > Command Line > Additional Options entry box, but
it serves the use case where a user switches back and forth
between the toolsets in their vcxproj, but where cl.exe
won't accept some options that clang-cl will. In this case
you can pass those options in the clang-cl additional options
and whenever clang-cl is disabled (or the other toolset is
selected entirely), those options won't get passed at all.

Revert "[SCEV][NFC] Check NoWrap flags before lexicographical comparison of SCEVs"
This reverts r319889.
Unfortunately, wrapping flags are not a part of SCEV's identity (they
do not participate in computing a hash value or in equality
comparisons) and in fact they could be assigned after the fact w/o
rebuilding a SCEV.
Grep for const_cast's to see quite a few of examples, apparently all
for AddRec's at the moment.
So, if 2 expressions get built in 2 slightly different ways: one with
flags set in the beginning, the other with the flags attached later
on, we may end up with 2 expressions which are exactly the same but
have their operands swapped in one of the commutative N-ary
expressions, and at least one of them will have "sorted by complexity"
invariant broken.
2 identical SCEV's won't compare equal by pointer comparison as they
are supposed to.
A real-world reproducer is added as a regression test: the issue
described causes 2 identical SCEV expressions to have different order
of operands and therefore compare not equal, which in its turn
prevents LoadStoreVectorizer from vectorizing a pair of consecutive
loads.
On a larger example (the source of the test attached, which is a
bugpoint) I have seen even weirder behavior: adding a constant to an
existing SCEV changes the order of the existing terms, for instance,
getAddExpr(1, ((A * B) + (C * D))) returns (1 + (C * D) + (A * B)).

[llvm-mca] Introduce the llvm-mca library and organize the directory accordingly. NFC.
Summary:
This patch introduces llvm-mca as a library. The driver (llvm-mca.cpp), views, and stats, are not part of the library.
Those are separate components that are not required for the functioning of llvm-mca.
The directory has been organized as follows:
All library source files now reside in:
- `lib/HardwareUnits/` - All subclasses of HardwareUnit (these represent the simulated hardware components of a backend).
(LSUnit does not inherit from HardwareUnit, but Scheduler does which uses LSUnit).
- `lib/Stages/` - All subclasses of the pipeline stages.
- `lib/` - This is the root of the library and contains library code that does not fit into the Stages or HardwareUnit subdirs.
All library header files now reside in the `include` directory and mimic the same layout as the `lib` directory mentioned above.
In the (near) future we would like to move the library (include and lib) contents from tools and into the core of llvm somewhere.
That change would allow various analysis and optimization passes to make use of MCA functionality for things like cost modeling.
I left all of the non-library code just where it has always been, in the root of the llvm-mca directory.
The include directives for the non-library source file have been updated to refer to the llvm-mca library headers.
I updated the llvm-mca/CMakeLists.txt file to include the library headers, but I made the non-library code
explicitly reference the library's 'include' directory. Once we eventually (hopefully) migrate the MCA library
components into llvm the include directives used by the non-library source files will be updated to point to the
proper location in llvm.

when running LLDB on a CI node, the syntax highlighter will not be deactivated by

actually exposes itself as dumb).
This patch now relies on the LLVM code for detecting color support which is more
reliable. We now also correctly actually initialize the `m_supports_colors` variable in `File`.
`m_supports_colors` was so far uninitialized, but the code path that uses `m_supports_colors`
was also dead so the sanitizers didn't sound an alarm.
The old check that compares `TERM` is not removed by this patch as the new LLVM code

[NFC] Split logic of ImplicitControlFlowTracking to allow generalization
We have a class `ImplicitControlFlowTracking` which allows us to keep track of
instructions that can abnormally exit and answer queries like "whether or not
there is side-exiting instruction above this instruction in its block".
We may want to have the similar tracking for other types of "special" instructions,
for example instructions that write memory.
This patch separates ImplicitControlFlowTracking into two classes, isolating all
general logic not related to implicit control flow into its parent class. We can
later make another child of this class to keep track of instructions that write
memory.
The motivation for that is that we want to make these checks efficiently in the

[COFF] Support MinGW automatic dllimport of data
Normally, in order to reference exported data symbols from a different
DLL, the declarations need to have the dllimport attribute, in order to
use the __imp_<var> symbol (which contains an address to the actual
variable) instead of the variable itself directly. This isn't an issue
in the same way for functions, since any reference to the function without
the dllimport attribute will end up as a reference to a thunk which loads
the actual target function from the import address table (IAT).
GNU ld, in MinGW environments, supports automatically importing data
symbols from DLLs, even if the references didn't have the appropriate
dllimport attribute. Since the PE/COFF format doesn't support the kind
of relocations that this would require, the MinGW's CRT startup code
has an custom framework of their own for manually fixing the missing
relocations once module is loaded and the target addresses in the IAT
are known.
For this to work, the linker (originall in GNU ld) creates a list of
remaining references needing fixup, which the runtime processes on
startup before handing over control to user code.
While this feature is rather controversial, it's one of the main features
allowing unix style libraries to be used on windows without any extra
porting effort.
Some sort of automatic fixing of data imports is also necessary for the
itanium C++ ABI on windows (as clang implements it right now) for importing
vtable pointers in certain cases, see D43184 for some discussion on that.
The runtime pseudo relocation handler supports 8/16/32/64 bit addresses,
either PC relative references (like IMAGE_REL_*_REL32*) or absolute
references (IMAGE_REL_AMD64_ADDR32, IMAGE_REL_AMD64_ADDR32,
IMAGE_REL_I386_DIR32). On linking, the relocation is handled as a
relocation against the corresponding IAT slot. For the absolute references,
a normal base relocation is created, to update the embedded address
in case the image is loaded at a different address.
The list of runtime pseudo relocations contains the RVA of the
imported symbol (the IAT slot), the RVA of the location the relocation
should be applied to, and a size of the memory location. When the
relocations are fixed at runtime, the difference between the actual
IAT slot value and the IAT slot address is added to the reference,
doing the right thing for both absolute and relative references.
With this patch alone, things work fine for i386 binaries, and mostly
for x86_64 binaries, with feature parity with GNU ld. Despite this,
there are a few gotchas:
- References to data from within code works fine on both x86 architectures,
since their relocations consist of plain 32 or 64 bit absolute/relative
references. On ARM and AArch64, references to data doesn't consist of
a plain 32 or 64 bit embedded address or offset in the code. On ARMNT,
it's usually a MOVW+MOVT instruction pair represented by a
IMAGE_REL_ARM_MOV32T relocation, each instruction containing 16 bit of
the target address), on AArch64, it's usually an ADRP+ADD/LDR/STR
instruction pair with an even more complex encoding, storing a PC
relative address (with a range of +/- 4 GB). This could theoretically
be remedied by extending the runtime pseudo relocation handler with new
relocation types, to support these instruction encodings. This isn't an
issue for GCC/GNU ld since they don't support windows on ARMNT/AArch64.
- For x86_64, if references in code are encoded as 32 bit PC relative
offsets, the runtime relocation will fail if the target turns out to be
out of range for a 32 bit offset.
- Fixing up the relocations at runtime requires making sections writable
if necessary, with the VirtualProtect function. In Windows Store/UWP apps,
this function is forbidden.
These limitations are addressed by a few later patches in lld and
llvm.

Summary:
Previously most CPUs inherited cmov support through Feature64Bit(or FeatureCMPXCHG16HB implying Feature64Bit) or FeatureSSE1.
This has the surprising side effect that -mattr=-cmov causes an assert to fire in 64-bit mode because it clears the Feature64Bit. Or in 32-bit mode, -mattr=-cmov disables any sse/avx features which seems surprising.
This patch removes the implication and instead updates hasCMOV in X86Subtarget to check SSE1 or is64Bit in addition to the regular cmov flag. This should keep most things working the way they did before. I don't believe there is a way to specific "-cmov" directly from clang so this should only effect our lower level tools.
This does stop -mattr=cx16(cmpxchg16b) from implying cmov is enabled via the 64bit flag as you can see from one of the changed tests. But that was a 32-bit test so I don't know why it enabled cx16 anyway.

Summary:
The only time vector SMUL_LOHI/UMUL_LOHI nodes are created is during division/remainder lowering. If its created before op legalization, generic DAGCombine immediately turns that SMUL_LOHI/UMUL_LOHI into a MULHS/MULHU since only the upper half is used. That node will stick around through vector op legalization and will be turned back into UMUL_LOHI/SMUL_LOHI during op legalization. It will then be custom lowered by the X86 backend. Due to this two step lowering the vector shuffles created by the custom lowering get legalized after their inputs rather than before. This prevents the shuffles from being combined with any build_vector of constants.
This patch uses changes vXi32 to use MULHS/MULHU instead. This is what the later DAG combine did anyway. But by skipping the change back to UMUL_LOHI/SMUL_LOHI we lower it before any constant BUILD_VECTORS. This allows the vector_shuffle creation to constant fold with the build_vectors.
