These tests fail for developers who place their build directories under the
llvm root directory because llvm's own .clang-format file will be found.
Anyway these cases are covered by FormatStyle.GetStyleOfFile tests
(FormatTest.cpp).

To ensure optimization level doesn't pessimize the -fstandalone-debug
vtable debug info optimization (where class definitions are only emitted
where the vtable is emitted - reducing redundant debug info) ensure the
debug info class definition is still omitted when an
available_externally vtable definition is emitted for optimization
purposes.

Summary:
Specifically, we upgrade llvm.nvvm.:

 * brev{32,64}
 * clz.{i,ll}
 * popc.{i,ll}
 * abs.{i,ll}
 * {min,max}.{i,ll,u,ull}
 * h2f

These either map directly to an existing LLVM target-generic
intrinsic or map to a simple LLVM target-generic idiom.

In all cases, we check that the code we generate is lowered to PTX as we
expect.

These builtins don't need to be backfilled in clang: They're not
accessible to user code from nvcc.

For a << b (as original vec_sl does), if b >= sizeof(a) * 8, the
behavior is undefined. However, Power instructions do define the
behavior, which is equivalent to a << (b % (sizeof(a) * 8)).

This patch changes altivec.h to use a << (b % (sizeof(a) * 8)), to
ensure the consistent semantic of the instructions. Then it combines
the generated multiple instructions back to a single shift.

This patch handles left shift only. Right shift, on the other hand, is
more complicated, considering arithematic/logical right shift.

Summary:
rL292562 added a fix to always format if the fallback style is set to "none".
In test/Format/style-on-command-line.cpp:19 is redundant, since -fallback-style
has a default value of LLVM set in ClangFormat.cpp:72.

@amaiorano: I believe that the rest of the test cases still cover your change in
case the fallback style is explicitly set to "none". Please, if this is not the
case, initiate a discussion.

Summary: Instead of picking the buffer file coding system, always use utf-8-unix for communicating with clang-format.  This is fine because clang-format never actually reads the file to be formatted, only standard input.  This is a bit simpler (process coding system is now a constant) and potentially faster, as utf-8-unix is Emacs's internal coding system.  Also add an end-to-end test that actually invokes clang-format.

This is another follow-up to r246338. I had assumed methods were already

Under this defect resolution, the injected-class-name of a class or class
template cannot be used except in very limited circumstances (when declaring a
constructor, in a nested-name-specifier, in a base-specifier, or in an
elaborated-type-specifier). This is apparently done to make parsing easier, but
it's a pain for us since we don't know whether a template-id using the
injected-class-name is valid at the point when we annotate it (we don't yet
know whether the template-id will become part of an elaborated-type-specifier).

As a tentative resolution to a perceived language defect, mem-initializer-ids
are added to the list of exceptions here (they generally follow the same rules
as base-specifiers).

When the reference to the injected-class-name uses the 'typename' or 'template'
keywords, we permit it to be used to name a type or template as an extension;
other compilers also accept some cases in this area. There are also a couple of
corner cases with dependent template names that we do not yet diagnose, but
which will also get this treatment.

Summary:
SamplePGO uses profile with debug info to collect profile. Unlike the traditional debugging purpose, sample pgo needs more accurate debug info to represent the profile. We add -femit-accurate-debug-info for this purpose. It can be combined with all debugging modes (-g, -gmlt, etc). It makes sure that the following pieces of info is always emitted:

* start line of all subprograms
* linkage name of all subprograms
* standalone subprograms (functions that has neither inlined nor been inlined)
