Add __builtin_operator_new and __builtin_operator_delete, which act like calls
to the normal non-placement ::operator new and ::operator delete, but allow
optimizations like new-expressions and delete-expressions do.

Downgrade "definition of dllimport static field" error to warning for class templates (PR19902)

This allows us to compile the following kind of code, which occurs in MSVC
headers:

  template <typename> struct S {
    __declspec(dllimport) static int x;
  };
  template <typename T> int S<T>::x;

The definition works similarly to a dllimport inline function definition and
gets available_externally linkage.

Remove the last remaining llvm/Config/config.h includes

This corrects long-standing misuses of LLVM's internal config.h.

In most cases the public llvm-config.h header was intended and we can now
remove the old hacks thanks to LLVM r210144.

The config.h header is private, won't be installed and should no longer be
included by clang or other modules.

Refactor and generalize GetAddrOfConstantString and GetAddrOfConstantStringFromLiteral.

Share mode code between these functions and re-structure them in a way
which shows how similar they actually are. The latter function works well
with literals of multi-byte chars and does a GlobalVariable name mangling
(if global strings are non-writable).

No functionality change.

[ubsan] Don't add a --dynamic-list for ubsan symbols when building a shared
library. That results in the linker resolving all references to weak symbols in
the DSO to the definition from within that DSO. Ironically, this rarely causes
observable problems, except that it causes ubsan's own dynamic type check to
spuriously fail (because we fail to properly merge type_info object names).

Flush C stdio streams upon process termination

Due to what can only be described as a CRT bug, stdout and amazingly
even stderr are not always flushed upon process termination, especially
when the system is under high threading pressure.  I have found two
repros for this:

1) In lib\Support\Threading.cpp, change sys::Mutex to an
std::recursive_mutex and run check-clang.  Usually between 30 and 40
tests will fail.

2) Add OutputDebugStrings in code that runs during static initialization
and static shutdown.  This will sometimes generate similar failures.

After a substantial amount of troubleshooting and debugging, I found
that I could reproduce this from the command line without running
check-clang.  Simply make the mutex change described in #1, then
manually run the following command many times by running it once, then
pressing Up -> Enter very quickly:

D:\src\llvm\build\vs2013\Debug\bin\c-index-test.EXE -cursor-at=D:\src\llvm\tools\clang\test\Index\targeted-preamble.h:2:15 D:\src\llvm\tools\clang\test\Index\targeted-cursor.c -include D:\src\llvm\build\vs2013\tools\clang\test\Index\Output\targeted-cursor.c.tmp.h -Xclang -error-on-deserialized-decl=NestedVar1      -Xclang -error-on-deserialized-decl=TopVar    | D:\src\llvm\build\vs2013\Debug\bin\FileCheck.EXE D:\src\llvm\tools\clang\test\Index\targeted-cursor.c -check-prefix=PREAMBLE-CURSOR1

Sporadically they will fail, and attaching a debugger to a failed
instance indicates that stdin of FileCheck.exe is empty.

Note that due to the repro in #2, we can rule out a bug in the STL's
mutex implementation, and instead conclude that this is a real flake in
the windows test harness.

Test Plan:
Without patch: Ran check-clang 10 times and saw over 30 Unexpected failures on every run.
With patch: Ran check-clang 10 times and saw 0 unexpected failures across all runs.
