Restore r184205 and associated commits (after commit of r185290)

This allows clang to use the backend parameter attribute 'returned' when generating 'this'-returning constructors and destructors in ARM and MSVC C++ ABIs.

InitListExpr.

Following the modification introduced in llvm by commit 185311

The build system is currently miss-identifying GNU/kFreeBSD as FreeBSD.
This kind of simplification is sometimes useful, but in general it's not correct. 

As GNU/kFreeBSD is an hybrid system, for kernel-related issues we want to match the
build definitions used for FreeBSD, whereas for userland-related issues we want to
match the definitions used for other systems with Glibc.

The current modification adjusts the build system so that they can be distinguished,
and explicitly adds GNU/kFreeBSD to the build checks in which it belongs.

Fixes bug #16445.

Patch by Robert Millan in the context of Debian.

Fix braced-list detection in lieu of trailing comments.

Before:
DoSomethingWithVector({
} /* No data */);
After:
DoSomethingWithVector({} /* No data */);

Keep space between pointer and block comment.

Before: void f(int */* unused */) {}
After:  void f(int * /* unused */) {}

The previous version seems to be valid C++ code but confuses many syntax
highlighters.

Don't add an extra space before ellipsis after pointers.

Before (for styles where the pointer binds to the type):
template <class... Ts> void Foo(Ts... ts) {}
template <class... Ts> void Foo(Ts* ... ts) {}
After:
template <class... Ts> void Foo(Ts... ts) {}
template <class... Ts> void Foo(Ts*... ts) {}

clang/test/lit.cfg: Improve is_filesystem_case_insensitive() to work properly on cygwin.

Cygwin does not accept the form /CYGDRIVE/X/PATH/TO/FILE against /cygdrive/X/PATH/TO/FILE.
"cygdrive" must be lower-cased.

Don't align "} // namespace" comments.

This is not all bad, but people are often surprised by it.

Before:
namespace {
int SomeVariable = 0; // comment
}                     // namespace

After:
namespace {
int SomeVariable = 0; // comment
} // namespace

Avoid column limit violation in block comments in certain cases.

Summary:
Add penalty when an excessively long line in a block comment can not be
broken on a leading whitespace. Lack of this addition can lead to severe column
width violations when they can be easily avoided.
