Clang used a custom implementation of lookup when handling designated
initializers. The custom code was not particularly optimized and relied
on standard lookup for typo-correction anyway.
This custom code has to go, it doesn't properly support MSVC-style
anonymous structs embedded inside other records; replace it with the
typo-correction path.
This has the side effect of speeding up semantic handling of the fields
for a designated initializer while simplifying the code at the same
time.
This fixes PR20573.

Just like with -finput-charset=UTF-8 in review http://reviews.llvm.org/D4347, I think we should just ignore it when UTF-8 is provided.

In cases like:
struct C { ~C(); }
void f(C c = C());
void t() {
f();
}
We currently do not add the CXXBindTemporaryExpr for the temporary (the
code mentions that as the default parameter expressions are owned by
the declaration, we'd otherwise add the same expression multiple times),
but we add the temporary destructor pointing to the CXXBindTemporaryExpr.
We need to fix that before we can re-enable the assertion.

Added K&R style. It could be enabled by the following option:
```
BreakBeforeBraces: KernighanRitchie
```
This style is like `Attach`, but break *only* before function
declarations.
As I can see, no additional logic required to support this style, any
style different from other styles automagically satisfies K&R.

We had two bugs:
- We wouldn't properly warn when a struct/union/enum was mentioned
inside of a record definition if no declarator was provided. We
should have mentioned that this declaration declares nothing.
- We didn't properly support Microsoft's extension where certain
declspecs without declarators would act as anonymous structs/unions.
* We completely ignored the case where such a declspec could be a
union.
* We didn't properly handle the case where a record was defined inside
another record:
struct X {
int a;
struct Y {
int b;
};
};

After post-commit review and community discussion, this seems like a

one, perform the import if the types match even if the imported declaration is
hidden. Otherwise, NamedDecl::declarationReplaces will drop one of the name
lookup entries, making the typedef effectively inaccessible from one of the

While the test was already requiring shell-preserves-root (such as the
internal shell), it wasn't aware that the MSYS 1.0 env command knows how
to expand root by itself!
From cmd.exe try:
env SDKROOT=/ cmd //c echo %SDKROOT%
And get:
C:/MINGW/MSYS/1.0
To be certain we have a good 'env' program the test now requires a shell.

Suprisingly the normalize_separators() was no-op when LLVM_ON_WIN32.
Its replacement native() does change path separators into \ as expected,
breaking these tests.
I had fixed the tests by #ifndef LLVM_ON_WIN32 on the native call,
to match the previous behaviour.
If this logic is not used on Windows host, it might be completely
deleted as there should not be windows path seperators on Linux hosts.
I can't test on Linux but if someone can run tests on Linux after
commenting out the line
llvm::sys::path::native(NormalizedPath);
and the tests pass, the whole if (LangOpts.MSVCCompat) could be deleted.

I reverted one of the added tests from r215261 in r215274, since it
was failing on quite a few bots. It looks like this wasn't sufficient,
as we're still getting failures on windows, like the following:
http://bb.pgr.jp/builders/ninja-x64-msvc-RA-centos6/builds/5378
I'm reverting this entire commit so the bots aren't blocked on these
failures.
This reverts commit r215261.

Summary:
This flag can be used to force linking of CXX-specific parts
of sanitizer runtimes into the final executable. It gives more precise
control than --driver-mode=g++ and comes handy when user links several
object files with sanitized C++ code into an executable, but wants
to provide libstdc++ himself, instead of relying on Clang dirver's
behavior.

macro arguments.
Previously, these warnings skipped any code in a macro expansion. Preform an
additional check and warn when the expression and context locations are both
in the macro argument.
The most obvious case not caught is passing a pointer directly to a macro,
i.e 'assert(&array)' but 'assert(&array && "valid array")' is caught. This is
because macro arguments are not typed and the conversion happens inside the
macro.
