clang/test/CodeGenCXX/debug-info-class.cpp: Tweak to unbreak test for a few targets.

  - Relax a expression for arm-gnueabi.
  - Exclude msvc to limit target triplets to add limited a few targets.
    Feel free to remove actions if guys thought they redundant.

Fix bug in formatting of nested initializers.

We can now format:
SomeArrayOfSomeType a = { { { 1, 2, 3 } }, { { 1, 2, 3 } },
                          { { 111111111111111111111111111111,
                              222222222222222222222222222222,
                              333333333333333333333333333333 } },
                          { { 1, 2, 3 } }, { { 1, 2, 3 } } };

Before, we did strange things there.

CodeGen: Implement hint values for dynamic_cast as described in the Itanium C++ ABI.

This can yield dramatic speedups of dynamic_cast for simple inheritance trees,
at least with libsupc++. Neither libcxxabi nor libcxxrt make use of this
hint currently, it was never implemented because clang didn't support it.

There was some concern about the number of class hierarchy walks this change
introduces. If it turns out to be an issue we can add caching either at the cast
pair level or even deeper, but we also do a lot of walks in Sema so this
codepath is probably fairly optimized already.

DeclPrinter: fix CXXConstructExpr printing with implicit default argument

This is an improvement of r173630, that handles the following case:

  struct VirualDestrClass
  {
    VirualDestrClass(int arg);
    virtual ~VirualDestrClass();
  };

  struct ConstrWithCleanupsClass
  {
    ConstrWithCleanupsClass(const VirualDestrClass& cplx = VirualDestrClass(42));
  };

  ConstrWithCleanupsClass cwcNoArg;

That was printed as:

  ConstrWithCleanupsClass cwcNoArg();

Restructuring of token annotation for formatting.

This combines several changes:
* Calculation token type (e.g. for * and &) in the AnnotatingParser.
* Calculate the scope binding strength in the AnnotatingParser.
* Let <> and [] scopes bind stronger than () and {} scopes.
* Add minimal debugging output.

Fix an error in formatting of for-loops.

Two minor changes:
* Slight penalty for breaking at "," as opposed to ";".
* Don't apply bin-packing rules to for-loops.

Before:
for (int aaaaaa = aaaaaaaaaa; aaaaaa < bbbbbbbb; ++aaaaaa,
         ++ccccccccccccccc) {}

After:
for (int aaaaaa = aaaaaaaaaa; aaaaaa < bbbbbbbb;
     ++aaaaaa, ++ccccccccccccccc) {}

Improve handling of trailing block comments.

We can now (even in non-bin-packing modes) format:
someFunction(1, /* comment 1 */
             2, /* comment 2 */
             3, /* comment 3 */
             aaa);
