Referencing a dllimported vtable is impossible in a constexpr
constructor. It would be friendlier to C++ programmers if we
synthesized a copy of the vftable which referenced imported virtual
functions. This would let us initialize the object in a way which
preserves both the intent to import functionality from another DLL while
also making constexpr work.

"main include" that will be the 1st include (category 0).
Because the clang-format visual studio extension does not pass the file
name and use the standard input, sort include cannot find a "main
include":
Testing fix on llvm\tools\clang\lib\Format\Format.cpp:
Original file:
#include "clang/Format/Format.h"
...
#include "clang/Basic/SourceManager.h"
#include "clang/Lex/Lexer.h"
Without fix, selecting the includes and running visual studio
clang-format:
...
#include "clang/Basic/SourceManager.h"
#include "clang/Format/Format.h"
#include "clang/Lex/Lexer.h"
With fix, selecting the includes and running visual studio clang-format:
#include "clang/Format/Format.h"
...
#include "clang/Basic/SourceManager.h"
#include "clang/Lex/Lexer.h"
Test 2 with main header not at the start:
Original file:
...
#include "clang/Format/Format.h"
#include "clang/Basic/SourceManager.h"
#include "clang/Lex/Lexer.h"
Without fix, selecting the includes and running visual studio
clang-format:
...
#include "clang/Basic/SourceManager.h"
#include "clang/Format/Format.h"
#include "clang/Lex/Lexer.h"
With fix, selecting the includes and running visual studio clang-format:
#include "clang/Format/Format.h"

r257357 fixed clang to warn on integer overflow in struct initializers.
However, it didn't warn when a struct had a nested initializer. This
commit makes changes in Sema::CheckForIntOverflow to handle nested
initializers.
For example:
struct s {
struct t {
unsigned x;
} t;
} s = {
{
.x = 4 * 1024 * 1024 * 1024
}
};

For multi-stage builds we need to pass any overridden source directory variables. Without passing these the subsequent stages won't find the project sources.

I had hoped this would work from a single cache file, but turns out there is a bug I can't quite figure out relating to passing list arguments to recursive CMake invocations.
This change works around that.

This is the third time it has crossed the 2^16 section limit. We've
already spent time optimizing this file to reduce template
instantiations, and it's not clear that there is anymore low hanging
fruit.

This builds on the support being added to LLVM to import and export
registries from DLLs. This will allow us to pick up the registry
entries added in the DLL's copy of FrontendPluginRegistry.
This will allow us to use plugins on Windows using:
$ clang-cl -Xclang -load -Xclang plugin.dll \
-Xclang -add-plugin -Xclang foo

While this won't help fix things like the bug that r260219 addressed, it
seems like good tidy up to have anyway.
(it might be nice if "makeArrayRef" always produced a MutableArrayRef &
let it decay to an ArrayRef when needed - then I'd use that for the
MutableArrayRefs in this patch)
If we had std::dynarray I'd use that instead of unique_ptr+size_t,
ideally (but then it'd have to be threaded down through the Preprocessor
all the way - no idea how painful that would be)

This cache file can be used to generate a 3-stage clang build. You can configure using the following CMake command:
cmake -C <path to clang>/cmake/caches/3-stage.cmake -G Ninja <path to llvm>
You can then run "ninja stage3-clang" to build stage1, stage2 and stage3 clangs.
This is useful for finding non-determinism the compiler by verifying that stage2 and stage3 are identical.
