593f993a68 Implement C++03 [dcl.init]p5's checking for value-initialization of references
properly, rather than faking it up by pretending that a reference member makes
the default constructor non-trivial. That leads to rejects-valids when putting
such types inside unions.

3a02247dc9 Sort all of Clang's files under 'lib', and fix up the broken headers
uncovered.

This required manually correcting all of the incorrect main-module
headers I could find, and running the new llvm/utils/sort_includes.py
script over the files.

I also manually added quite a few missing headers that were uncovered by
shuffling the order or moving headers up to be main-module-headers.

a1c27eb8dd [PCH] Write out the ClassTemplateDecl::Common::InjectedClassNameType type
reference instead of relying on computing it.

In general, if storage is no issue, it is preferable to deserialize info from
the PCH instead of trying to recompute it after the PCH was loaded.

The incentive to change this now was due to r155303 changing how friend template
classes in dependent contexts are handled; such classes can now be chained to
a previous template class but the computed InjectedClassNameType may be different
due to the extra template parameters from the dependent context.

The new handling requires more investigation but, in the meantime, writing out
InjectedClassNameType fixes PCH issue in rdar://12627738.

0d54a17b52 Set a special flag in class metadata when an Objective-C class
has ivars that require destruction, but none that require anything
except zero-initialization.  This is common in ARC and (when true
throughout a class hierarchy) permits the elimination of an
unnecessary message-send during allocation.

d01e83ab3e Rename ObjCMethodDecl::isSynthesized to isPropertyAccessor.
This more accurately reflects its use: this flag is set when a method
matches the getter or setter name for a property in the same class,
and does not actually specify whether or not the definition of the method
will be synthesized (either implicitly or explicitly with @synthesize).

This renames the setter and backing field as well, and changes the
(soon-to-be-obsolete?) XML dump format to use 'property_accessor'
instead of 'synthesized'.

a6017bbd52 When we load a function or method body from an AST file, we check
whether that function/method already has a body (loaded from some
other AST file), as introduced in r165137. Delay this check until
after the redeclaration chains have been wired up.

While I'm here, make the loading of method bodies lazy.

6fa1682368 [PCH] After deserializing a DeclContext, if it has external lexical decls but not
external visible decls, call DeclContext::setMustBuildLookupTable so that the
"lazy decls" bit of the LookupPtr is set.

Previously, in non-C++, if there were no new declarations causing the "lazy decls" bit
to be set, then DeclContext::lookups_begin() would fail to return the decls from the PCH.

1fde8ece37 PR9023: A template template parameter whose template parameter list contains an
unexpanded parameter pack is a pack expansion. Thus, as with a non-type template
parameter which is a pack expansion, it needs to be expanded early into a fixed
list of template parameters.

Since the expanded list of template parameters is not itself a parameter pack,
it is permitted to appear before the end of the template parameter list, so also
remove that restriction (for both template template parameter pack expansions and
non-type template parameter pack expansions).

33b4bfcef5 [AST/libclang] Fix the selector locations that are reported for a
method definition that has its '{' attached to the method name without
a space.

With a method like:

-(id)meth{
.....
}

the logic in ObjCMethodDecl that determined the selector locations got
confused because it was initialized based on an end location for '{' but
that end location changed to '}' after the method was finished.

Fix this by having an immutable end location for the declarator and
for getLocEnd() get the end location from the body itself.

4086a13df8 Remove CXXRecordDecl flags which are unused after r158289.
We need an efficient mechanism to determine whether a defaulted default
constructor is constexpr, in order to determine whether a class is a literal
type, so keep the incrementally-built form on CXXRecordDecl. Remove the
on-demand computation of same, so that we only have one method for determining
whether a default constructor is constexpr. This doesn't affect correctness,
since default constructor lookup is much simpler than selecting a constructor
for copying or moving.

We don't need a corresponding mechanism for defaulted copy or move constructors,
since they can't affect whether a type is a literal type. Conversely, checking
whether such functions are constexpr can require non-trivial effort, so we defer
such checks until the copy or move constructor is required.

Thus we now only compute whether a copy or move constructor is constexpr on
demand, and only compute whether a default constructor is constexpr in advance.
This is unfortunate, but seems like the best solution.

ed90df3800 Generate an AST for the conversion from a lambda closure type to a
block pointer that returns a block literal which captures (by copy)
the lambda closure itself. Some aspects of the block literal are left
unspecified, namely the capture variable (which doesn't actually
exist) and the body (which will be filled in by IRgen because it can't
be written as an AST).

Because we're switching to this model, this patch also eliminates
tracking the copy-initialization expression for the block capture of
the conversion function, since that information is now embedded in the
synthesized block literal. -1 side tables FTW.

680e9e018d Improve our handling of lambda expressions that occur within default
arguments. There are two aspects to this:

  - Make sure that when marking the declarations referenced in a
  default argument, we don't try to mark local variables, both because
  it's a waste of time and because the semantics are wrong: we're not
  in a place where we could capture these variables again even if it
  did make sense.
  - When a lambda expression occurs in a default argument of a
  function template, make sure that the corresponding closure type is
  considered dependent, so that it will get properly instantiated. The
  second bit is a bit of a hack; to fix it properly, we may have to
  rearchitect our handling of default arguments, parsing them only
  after creating the function definition. However, I'd like to
  separate that work from the lambdas work.

7fcbd902b4 Implement name mangling for lambda expressions that occur within the
default arguments of function parameters. This simple-sounding task is
complicated greatly by two issues:

  (1) Default arguments aren't actually a real context, so we need to
  maintain extra state within lambda expressions to track when a
  lambda was actually in a default argument.
  (2) At the time that we parse a default argument, the FunctionDecl
  doesn't exist yet, so lambda closure types end up in the enclosing
  context. It's not clear that we ever want to change that, so instead
  we introduce the notion of the "effective" context of a declaration
  for the purposes of name mangling.
