Add a test case for the 'vec_type_hint' attribute that was introduced in
r176686. I missed this file in the previous commit.

Partly revert "Move clang tests that depend on llvm/ADT/Statistic.h to a subdir".

This reverts commit 176730, and uses "REQUIRES: asserts" instead.

Improve the caching of debuginfo Objective C interface types.
Generate forward declarations that are RAUW'd by finalize().
We thus avoid outputting the same type several times in multiple
stages of completion.

Disallow using -fmodules with -no-integrated-as.

Modules enables features such as auto-linking, and we simply do not want to
support a matrix of subtly enabled/disabled features depending on whether or
not a user is using the integrated assembler.

It isn't clear if this is the best place to do this check.  For one thing,
these kind of errors are not caught by the serialized diagnostics.

[analyzer] Look for calls along with lvalue nodes in trackNullOrUndefValue.

r176737 fixed bugreporter::trackNullOrUndefValue to find nodes for an lvalue
even if the rvalue node had already been collected. This commit extends that
to call statement nodes as well, so that if a call is contained within
implicit casts we can still track the return value.

No test case because node reclamation is extremely finicky (dependent on
how the AST and CFG are built, and then on our current reclamation rules,
and /then/ on how many nodes were generated by the analyzer core and the
current set of checkers). I consider this a low-risk change, though, and
it will only happen in cases of reclamation when the rvalue node isn't
available.

Remove driver support for Hexagon V2 and V3

Driver will now error when trying to compile for V2 or V3.

Removal of V2 and V3 support will allow us to simplify the hexagon
back-end.

Error if an extern C declaration matches a previous hidden extern C declaration.

Without this patch we produce an error for

extern "C" {
  void f() {
    extern int b;
  }
}
extern "C" {
  extern float b;
}

but not for

extern "C" {
  void f() {
    extern int b;
  }
}
extern "C" {
  float b;
}

Correctly compute linkage of decls forward declared extern C.

This fixes a crash in

namespace {
  struct X {};
}
extern "C" X test2_b;
X test2_b

before we would assign different linkages to each of the test2_b decls.

We already reported an error for

extern "C" {
  void test5_f() {
    extern int test5_b;
  }
}
static float test5_b;

This patch makes us report one for

extern "C" {
  void test6_f() {
    extern int test6_b;
  }
}
extern "C" {
  static float test6_b;
}

Not because we think the declaration would be extern C, but because of the rule:

An entity with C language linkage shall not be declared with the same name as an entity in global scope...

We were just not looking past the extern "C" to see if the decl was in global
scope.

Revert "Disallow using -fmodules with -no-integrated-as."

Per comment from Benjamin Kramer, this isn't portable (yet).  I'll come up
with a better fix.
