Apple's iOS, tvOS and watchOS simulator platforms have never been clearly
distinguished in the target triples. Even though they are intended to
behave similarly to the corresponding device platforms, they have separate
SDKs and are really separate platforms from the compiler's perspective.
Clang now defines a macro when building for one of these simulator platforms
(r297866) but that relies on the very indirect mechanism of checking to see
which option was used to specify the minimum deployment target. That is not
so great. Swift would also like to distinguish these simulator platforms in
a similar way, but unlike Clang, Swift does not use a separate option to
specify the minimum deployment target -- it uses a -target option to
specify the target triple directly, including the OS version number.
Using a different target triple for the simulator platforms is a much
more direct and obvious way to specify this. Putting the "simulator" in
the environment component of the triple means the OS values can stay the
same and existing code the looks at the OS field will not be affected.

Summary:
This operating system type represents the AMDGPU PAL runtime, and will
be required by the AMDGPU backend in order to generate correct code for
this runtime.
Currently it generates the same code as not specifying an OS at all.
That will change in future commits.

Summary:
Using c++11 enum classes ensures that only valid enum values are used
for ArchKind, ProfileKind, VersionKind and ISAKind. This removes the
need for checks that the provided values map to a proper enum value,
allows us to get rid of AK_LAST and prevents comparing values from
different enums. It also removes a bunch of static_cast
from unsigned to enum values and vice versa, at the cost of introducing
static casts to access AArch64ARCHNames and ARMARCHNames by ArchKind.
FPUKind and ArchExtKind are the only remaining old-style enum in
TargetParser.h. I think it's beneficial to keep ArchExtKind as old-style
enum, but FPUKind can be converted too, but this patch is quite big, so
could do this in a follow-up patch. I could also split this patch up a
bit, if people would prefer that.

Summary:
This patch updates Triple::isCompatibleWith to make armxx and thumbxx
triples compatible, as long as the subarch, vendor, os, envorionment and
object format match. Thumb/ARM code generation should be controlled
using the thumb-mode per-function target feature rather than by the
triple to allow mixing Thumb and ARM functions.
D33448 updates Clang's codegen to add thumb-mode for all functions with
armxx or thumbxx triples.

I did this a long time ago with a janky python script, but now
clang-format has built-in support for this. I fed clang-format every
line with a #include and let it re-sort things according to the precise
LLVM rules for include ordering baked into clang-format these days.
I've reverted a number of files where the results of sorting includes
isn't healthy. Either places where we have legacy code relying on
particular include ordering (where possible, I'll fix these separately)
or where we have particular formatting around #include lines that
I didn't want to disturb in this patch.
This patch is *entirely* mechanical. If you get merge conflicts or
anything, just ignore the changes in this patch and run clang-format
over your #include lines in the files.
Sorry for any noise here, but it is important to keep these things
stable. I was seeing an increasing number of patches with irrelevant
re-ordering of #include lines because clang-format was used. This patch
at least isolates that churn, makes it easy to skip when resolving
conflicts, and gets us to a clean baseline (again).

compatible target triple
Currently, an assertion fails in ThinLTOCodeGenerator::addModule when
the target triple of the module being added doesn't match that of the
one stored in TMBuilder. This patch relaxes the constraint and makes
changes to allow target triples that only differ in their version
numbers on Apple platforms, similarly to what r228999 did.

Summary:
For AMDGPU, we have been using the operating system component of the triple
for specifying the low-level runtime that is being used. The rationale for
this is that the host operating system (e.g. Linux) is irrelevant for GPU code,
since its execution enviroment will be mostly controled by the low-level runtime
being used to execute the code.
In most cases, higher level languages have their own runtime which is
implemented on top of the low-level runtime. The kernel ABIs of each
language mostly depend on the low-level runtime, but there may be some
slight differences between languages. OpenCL for example, may append
additional arguments to the kernel in order to pass values like global
offsets or buffers for printf. OpenMP, HCC, or other languages may want
to add their own values which differ from OpenCL.
The reason for adding a new opencl environment type is to make it possible for the backend
to distinguish between the ABIs of the higher-level languages and handle them correctly.
It seems cleaner to use the enviroment component for this rather than creating a new
OS type for every combination of low-level runtime / high-level language.

Since these are named nvvm_* rather than nvptx_*, we also need to

Summary:
This follows D14577 to treat ARMv6-J as an alias for ARMv6,
instead of an architecture in its own right.
The functional change is that the default CPU when targeting ARMv6-J
changes from arm1136j-s to arm1136jf-s, which is currently used as
the default CPU for ARMv6; both are, in fact, ARMv6-J CPUs.
The J-bit (Jazelle support) is irrelevant to LLVM, and it doesn't
affect code generation, attributes, optimizations, or anything else,
apart from selecting the default CPU.
