This arranges more of the Intel and AMD CPUs into fallthrough positions based on their features. We may be able to merge this new AMD set with the BTVER or BDVER sets but I didn't look that closely.

Summary:
For a lot of older CPUs we have a 1:1 mapping between CPU name and enum name. But many of them are effectively aliases of each other and as a result are always repeated together at every usage
This patch removes most of the duplication. It also uses StringSwitch::Cases to make the many to one mapping in the StringSwitch more obvious.

Introduce a new "export_as" directive for top-level modules, which
indicates that the current module is a "private" module whose symbols
will eventually be exported through the named "public" module. This is
in support of a common pattern in the Darwin ecosystem where a single
public framework is constructed of several private frameworks, with
(currently) header duplication and some support from the linker.

Summary:
The find_first_existing_file and find_first_existing_vc_file macros in
lib/Basic/CMakeLists.txt are removed. The macros are also defined in
{LLVM}/cmake/modules/AddLLVM.cmake for the same purpose. This change
serves the following 2 objectives:
1. To remove the redundant code in clang to use the same
macros in llvm,
2. The macros in AddLLVM.cmake can also handle repo for
displaying correct version information.

In patch r205628 using abs.[ds] instruction is forced, as they should behave
in accordance with flags Has2008 and ABS2008. Unfortunately for revisions
prior mips32r6 and mips64r6, abs.[ds] is not generating correct result when
working with NaNs. To generate a sequence which always produce a correct
result but also to allow user more control on how his code is compiled,
option -mabs is added where user can choose legacy or 2008.
By default legacy mode is used on revisions prior R6. Mips32r6 and mips64r6
use abs2008 mode by default.

OpenCL 2.0 atomic builtin functions have a scope argument which is ideally
represented as synchronization scope argument in LLVM atomic instructions.
Clang supports translating Clang atomic builtin functions to LLVM atomic
instructions. However it currently does not support synchronization scope
of LLVM atomic instructions. Without this, users have to use LLVM assembly
code to implement OpenCL atomic builtin functions.
This patch adds OpenCL 2.0 atomic builtin functions as Clang builtin
functions, which supports generating LLVM atomic instructions with
synchronization scope operand.
Currently only constant memory scope argument is supported. Support of
non-constant memory scope argument will be added later.

Targets.cpp is getting unwieldy, and even minor changes cause the entire thing
to cause recompilation for everyone. This patch bites the bullet and breaks
it up into a number of files.
I tended to keep function definitions in the class declaration unless it
caused additional includes to be necessary. In those cases, I pulled it
over into the .cpp file. Content is copy/paste for the most part,
besides includes/format/etc.

The patch adds support of i128 params lowering. The changes are quite trivial to
support i128 as a "special case" of integer type. With this patch, we lower i128
params the same way as aggregates of size 16 bytes: .param .b8 _ [16].
Currently, NVPTX can't deal with the 128 bit integers:
* in some cases because of failed assertions like
ValVTs.size() == OutVals.size() && "Bad return value decomposition"
* in other cases emitting PTX with .i128 or .u128 types (which are not valid [1])

Summary:
When searching for Git version control information, libBasic's CMake
checks for the path '.git/logs/HEAD'. However, when LLVM is included as
a Git submodule, this path does not exist. Instead, it contains a '.git'
file with the following:
```
gitdir: ../../.git/modules/external/llvm
```
Where '../..' is the relative path to the root repository that contains
the LLVM Git submodule.
Because of this discrepancy, `clang --version` does not output source
control information if built from a Git submodule.
To fix, check whether '.git' is a directory or a file. If it's a
directory, simply use the '.git/logs/HEAD' path. If it's a file, read it
and check for the tell-tale sign of a Git submodule: the text "gitdir:".
If it exists, follow that path and use the 'logs/HEAD' at that location
instead. This allows not only the correct revision information to be
retrieved, but also uses a file that will change with each source
control revision.
Test Plan:
1. Before applying this change, build Clang as a Git submodule in a repository
that places it in external/clang, and confirm no revision information
is output when `clang --version` is invoked (just "clang 5.0.0" is
output, no Git hashes).
2. Apply these changes and build Clang as a Git repository nested under
llvm/tools/clang, and confirm that `clang --version` displays correct
version information.
3. Apply these changes and build Clang as a Git submodule using the
structure described in (1), and confirm version control information
is output as in (2).
