docs: "clang tools" are not a different interface.

I spotted someone confused about this, so remove the heading to make it
clear that they really are a part of Tooling.

CodeGen/compound-assign-overflow.c: include stdint.h in freestanding mode

This hopefully fixes the ARM buildbot.

Change the data structure used in clang-format.

This is a first step towards supporting more complex structures such
as #ifs inside unwrapped lines. This patch mostly converts the array-based
UnwrappedLine into a linked-list-based UnwrappedLine. Future changes will
allow multiple children for each Token turning the UnwrappedLine into a
tree.

No functional changes intended.

Clear the LV cache when setting the instantiated from link.
Fixes pr14835.

Add missing spaces. This doesn't cause problems in practice because we only warn
about _Static_assert with -pedantic.

Don't put spaces around ##.

In Clang/LLVM this seems to be the more common formatting for ##s. There
might still be case that we miss, but we'll fix those as we go along.

Before:

  #define A(X)
    void function ## X();

After:

  #define A(X)
    void function##X();

clang-format can now format #defines.

Formatter: Add tests for some ObjC bits that happen to be formatted correctly.

Use Decl::getAvailability() rather than checking for the "unavailable"
attribute when determining whether we need to see an implementation of
a property. Fixes <rdar://problem/12958191>.

[libclang] In clang_equalCursors, clear out the "FirstInDeclGroup" part in a declaration cursor
before doing the comparison.

This is because we can't set "FirstInDeclGroup" consistently; for example, when visiting a DeclStmt we will set
it but we don't set it on the result of clang_getCursorDefinition for a reference of the same declaration.

[analyzer] Only include uniqueling location as issue_hash when available

This makes us more optimistic when matching reports in a changing code
base. Addresses Jordan's feedback for r171825.

Various tweaks and updates to the analyzer website.

Formatter: Format @ literals better. Array and dictionary literals need more work.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@171887 91177308-0d34-0410-b5e6-96231b3b80d8
Mark all subsequent decls used.

In the source

  static void f();
  static void f();
  template<typename T>
  static void g() {
    f();
  }
  static void f() {
  }
  void h() {
    g<int>();
  }

the call to f refers to the second decl, but it is only marked used at the end
of the translation unit during instantiation, after the third f decl has been
linked in.

With this patch we mark all subsequent decls used, so that it is easy to check
if a symbol is used or not.

Don't break after unary operators.

Before:
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa(aaaaaaaaaaaaaaaaaaaaaaaaaaaa, *
                                                 aaaaaaaaaaaaaaaaaaaaaaaaaaaaa);

aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa(
    aaaaaaaaaaaaaaaaaaaaaaaaaaaa, *aaaaaaaaaaaaaaaaaaaaaaaaaaaaa);

[analyzer] Bump down the max size of functions being analyzed.

With the new setting, we are not going to inline any functions that are
more than 50 basic blocks. (The analyzer is 20% faster on several
especially bad benchmarks with the new default.)
