DataFlowSanitizer: Replace non-instrumented aliases of instrumented functions, and vice versa, with wrappers.

DFSan changes the ABI of each function in the module.  This makes it possible
for a function with the native ABI to be called with the instrumented ABI,
or vice versa, thus possibly invoking undefined behavior.  A simple way
of statically detecting instances of this problem is to prepend the prefix
"dfs$" to the name of each instrumented-ABI function.

This will not catch every such problem; in particular function pointers passed
across the instrumented-native barrier cannot be used on the other side.
These problems could potentially be caught dynamically.

Summary:
These typically come from static data members of class template
specializations.  This accomplishes two things:

1. May expose GlobalOpt optimizations for Itanium C++ ABI code.
2. Works toward fixing double initialization in the Microsoft C++ ABI.

Test-time dependencies now live within test/clang-replace/Inputs which is more
in line with llvm and clang test suites.

Added 'Inputs' to the lit config's 'exclude' list as with llvm's lit.cfg since
test-time dependencies should not have any lit scripts within.

Zhihao Yuan noted that there were a few unneeded  statements.  Eliminated the unnecessary ones, and commented the ones that are there for non-obvious reasons such as to help things limp along in C++03 language mode.

This reverts commit r189017.

It broke the windows bots:
- http://bb.pgr.jp/builders/ninja-clang-i686-msc17-R/builds/4176
- http://bb.pgr.jp/builders/cmake-clang-i686-mingw32/builds/3837

Zhihao Yuan noted that a move assignment operation was missing from std::adjacent_difference.  Fixed.

David Blaikie suggested this test for detecting constexpr on the error_category default constructor.  Additionally I decided to make this constructor trivial as well, as I could not come up with a rationale for not doing so.  Fully tested with both current Apple clang and tip-of-trunk clang.

A single metadata will not span multiple lines. This also helps me with
my script to automatic update the testing cases.
A debug info testing case should have a llvm.dbg.cu.
Do not use hard-coded id for debug nodes.

Summary:
Refactor VariantMatcher to use an interface underneath.
It supports "Single" and "Polymorphic". Will support more in the future.

I was bound to screw this up somehow.

Thanks for pointing this out, Stephen. I think this is right now -- I
attempted to try all four valid combinations with both the autoconf and
CMake builds.

See also LLVM changes to the configure script.

llvm-svn: 189027

I don't actually have a version of autoconf so I edited configure directly
as well. It's copy-pasted so I think there was little margin for error.

DebugInfo: emit the definition of types when construction vtables are required as these types may never end up emitting the full class data

This might be able to be optimized further by only doing this in the
absence of a key function, but it doesn't look like GCC is doing that so
I'm not rushing to do it just yet.

Subdirectories of test/clang-replace contain test-time dependencies and not
more LIT tests. Tell LIT to ignore these directories from the test suite.

With this patch, braced lists (with more than 3 elements are formatted in a
column layout if possible). E.g.:

  static const uint16_t CallerSavedRegs64Bit[] = {
    X86::RAX, X86::RDX, X86::RCX, X86::RSI, X86::RDI,
    X86::R8,  X86::R9,  X86::R10, X86::R11, 0
  };

Required other changes:
- FormatTokens can now have a special role that contains extra data and can do
  special formattings. A comma separated list is currently the only
  implementation.
- Move penalty calculation entirely into ContinuationIndenter (there was a last
  piece still in UnwrappedLineFormatter).

The IncludeDirectives class helps with detecting and modifying #include
directives. For now it allows the users to add angled-includes in a source file.
This is a start for this class that will evolve in the future to add more
functionality.

This should fix the reverted commit r188791 (buildbot failures on Windows).
