'schedule' clause for combined directives requires additional processing. Special helper variable is generated, that is captured in the outlined parallel region for 'parallel for' region. This captured variable is used to store chunk expression from the 'schedule' clause in this 'parallel for' region.

The MachO toolchain has an isTargetIOSBased method, but it isn't
virtual so it isn't very meaningful to call it. After thinking about
this, I guess that putting this logic in the MachO class is a bit of a
layering violation anyway. Do this more like how we handle
AddLinkRuntimeLibArgs instead.

Compiler-rt's Profiling library isn't part of the stdlib, so -nostdlib
shouldn't prevent it from being linked. This makes Darwin behave like
other toolchains, and link in the profile runtime irrespective of
-nostdlib, since the resulting program can't be run unless you link
this.
I've also added a test to show that other toolchains already behave
like this.

Empty assembly string will not introduce assembly code in the output
binary and it is often used as a trick in the header to disable
optimizations. It doesn't conflict with the purpose of the option so it
is allowed with -fno-gnu-inline-asm flag.

This is necessary in order to allow the use of a constexpr member function, or
a member function with deduced return type, of a local class within a
surrounding instantiated function template specialization.
Patch by Michael Park!
This re-commits r236063, which was reverted in r236134, along with a fix for a
delayed template parsing bug that was exposed by this change.

Summary:
AsmLabel is heavily used in system level and firmware to redirect
function and access platform specific labels. They are also extensively
used in system headers which makes this option unusable for many
users. Since AsmLabel doesn't introduce any assembly code into the
output binary, it shouldn't be considered as inline-asm.

After mailing list discussion on 11-13 March we would prefer to stick to a
single spelling of the long option.
This reverts commit 30035fe1a7c759c89ee62eb46efce6b3790fcc08.

Specifically, calculate the deviation between the shortest and longest
element (which is used to prevent excessive whitespace) per column, not
overall. This automatically handles the corner cases of a single column
and a single row so that the actualy implementation becomes simpler.
Before:
vector<int> x = {1,
aaaaaaaaaaaaaaaaaaaaaa,
2,
bbbbbbbbbbbbbbbbbbbbbb,
3,
cccccccccccccccccccccc};
After:
vector<int> x = {1, aaaaaaaaaaaaaaaaaaaaaa,
2, bbbbbbbbbbbbbbbbbbbbbb,
3, cccccccccccccccccccccc};

Pull various parts of the UnwrappedLineFormatter into their own
abstractions. NFC.
There are two things left for subsequent changes (to keep this
reasonably small)
- the UnwrappedLineFormatter now has a bad name
- the UnwrappedLineFormatter::format function is still too large

We didn't supporting taking the address of virtual member functions
which overrode a method in a virtual base. We simply need to encode the
virtual base index in the member pointer.
This fixes PR23452.
N.B. There is no data member pointer side to this change because taking
the address of a virtual bases' data member gives you a member pointer
whose type is derived from the virtual bases' type, not the most derived
type.

MSVC 2015 renamed the symbol found by name lookup for 'std::terminate'
so we cannot rely on using '?terminate@@YAXXZ'. Furthermore, it seems
that 2015 will be the first release of MSVC which permits inlining a
function which is noexcept into a function which isn't. This is
implemented by creating a cleanup for the invoker which jumps to
__std_terminate. Clang's implementation of this aspect of the MSVC
scheme is slightly less efficient in this respect because we use a
catch handler configured as a catch-all handler instead.

Some compilers ignore everything after a semicolon in such inline asm
blocks and thus, the closing brace must not be moved to the previous
line.

This reverts commit 236854, which caused clang-format to always print
'{ "IncompleteFormat": false }' at the top of an incompletely formatted file.
This output causes problems e.g. in Polly's automatic formatting checks. Daniel
tried to fix this in 236867, but this fix had to be reverted due to buildbot
failures. I revert this change as well for now as it is Friday night and
unlikely to be fixed immediately.

This is a starting point for using the TargetParser in Clang, in a simple
enough part of the code that can be used without disrupting the crazy
platform support that we need to be compatible with other toolchains.
Also adding a few FIXME on obvious places that need replacing, but those
cases will indeed break a few of the platform assumptions, as arch/cpu names
change multiple times in the driver.
Finally, I'm changing the "neon-vfpv3" behaviour to match standard NEON, since
-mfpu=neon implies vfpv3 by default in both Clang and LLVM. That option
string is still supported as an alias to "neon".

Patch from Geoff Berry <gberry@codeaurora.org>
Fix BackendConsumer::EmitOptimizationMessage() to check if the
DiagnosticInfoOptimizationBase object has a valid location before
calling getLocation() to avoid dereferencing a null pointer inside
getLocation() when no debug info is present.
llvm-svn: 236898
Functions with available_externally linkage will not be emitted to object
files (they will just be undefined symbols), so it does not make sense to
put them in comdats.
Creates a second overload of maybeSetTrivialComdat that uses the GlobalObject
instead of the Decl, and uses that in several places that had the faulty
logic.
