Move the "->" to "." fixit from r186128 into a separate note since
recovery is not attempted with the fixit. Also move the associated test
case from FixIt/fixit.cpp to SemaCXX/member-expr.cpp since the fixit is
no longer automatically applied.

Fix member refs with using decl + anonymous union.

Make sure we call BuildFieldReferenceExpr with the appropriate decl
when a member of an anonymous union is made public with a using decl.
Also, fix a crash on invalid field access into an anonymous union.

Fixes PR16630.

Fix alignment of class derived from empty class.

The record layout code didn't properly take into account that
an empty class at offset 0 can have an alignment greater than 1.

Merge attributes on typedef decls.

Not completely sure this is right, but it's clearly better than what
we did before this commit (effectively dropping the attribute).

Limit number of bits in size representation so that bit size fit 64 bits.

ARM: implement low-level intrinsics for the atomic exclusive operations.

This adds three overloaded intrinsics to Clang:
    T __builtin_arm_ldrex(const volatile T *addr)
    int __builtin_arm_strex(T val, volatile T *addr)
    void __builtin_arm_clrex()

The intent is that these do what users would expect when given most sensible
types. Currently, "sensible" translates to ints, floats and pointers.

Fix test on release builds.

Unfortunately I don't think there's a good way to validate branch targets on
release builds. Fortunately it's a minor part of this test (and based on
generic code) so I don't mind dropping it.

clang-format: Improve detection of function types.

This fixes an incorrect detection that led to a formatting error.
Before:
  some_var = function (*some_pointer_var)[0];
After:
  some_var = function(*some_pointer_var)[0];

Fixes another hard to test problem with iterator invalidation.

As every match call can recursively call back into the memoized match
via a nested traversal matcher (for example:
stmt(hasAncestor(stmt(hasDescendant(stmt(hasDescendant(stmt()))))))),
and every memoization step might clear the cache, we must not store
iterators into the result cache when calling match on a submatcher.

Add more types to ASTNodeKind. Refactor common instantiation code.

Summary:
Add support for CXXCtorInitializer and TemplateArgument types to ASTNodeKind.
This change is to support more matchers from clang/ASTMatchers/ASTMatchers.h in the dynamic layer (clang/ASTMatchers/Dynamic).

Revamp the formatting of C++11 braced init lists.

The fundamental concept is:
Format as if the braced init list was a function call (with parentheses
replaced by braces). If there is no name/type before the opening brace
(e.g. if the braced list is nested), assume a zero-length identifier
just before the opening brace.

This behavior is gated on a new style flag, which for now replaces the
SpacesInBracedLists style flag. Activate this style flag for Google
style to reflect recent style guide changes.
