Argyrios Kyrtzidis e16a5300ba Keep track in chained PCH of implicit members that were added after the definition was completed.

Argyrios Kyrtzidis d170d844c4 Start fleshing out ASTMutationListener; notify when a tag definition is completed.
In that case a chained PCH will record the updates to the DefinitionData pointer of forward references.
If a forward reference mutated into a definition re-write it into the chained PCH, this is too big of a change.

Argyrios Kyrtzidis 65ad5691fd Put the mechanism in place to track modifications in an AST entity that were committed after
its initial creation/deserialization and store the changes in a chained PCH.

The idea is that the AST entities call methods on the ASTMutationListener to give notifications
of changes; the PCHWriter implements the ASTMutationListener interface and stores the incremental changes
of the updated entity. WIP

John McCall 457a04e3ce Substantially revise how clang computes the visibility of a declaration to
more closely parallel the computation of linkage.  This gets us to a state
much closer to what gcc emits, modulo bugs, which will undoubtedly arise in
abundance.

Douglas Gregor bff6203152 Always treat 'main' as an extern "C" function, so that we detect
redeclarations of main appropriately rather than allowing it to be
overloaded. Also, disallowing declaring main as a template.

Craig Silverstein 20f7ab72b1 The type-to-delete may not be a pointer if it's a dependent type.
Here's example code:
---
template<class T> class MyClass {
  struct S { };
  S* NewS() { return new S; }
  void DeleteS() { delete NewS(); }
};
---
CXXDeleteExpr::getDestroyedType() on the 'delete NewS()' expression
would crash before this change.  Now it returns a dependent type
object.  Solution suggested by dgregor.

Argyrios Kyrtzidis 0e88a565c0 Allow deserialization of just the fields of a record, when we want to iterate over them,
instead of deserializing the complete declaration context of the record.

Iterating over the fields of a record is very common (e.g to determine the layout), unfortunately we needlessly deserialize every declaration
that the declaration context of the record contains; this can be bad for large C++ classes that contain a lot of methods.
Fix this by allow deserialization of just the fields when we want to iterate over them.
Progress for rdar://7260160.

Douglas Gregor 52051cb173 Introduce a bit into Type that keeps track of whether there are any
unnamed or local types within that type. This bit is cached along with
the linkage of a type, so that it can be recomputed (e.g., when we see
that a typedef has given a name to an anonymous declaration).

Use this bit when checking C++03 [temp.arg.type]p2, so that we don't
walk template argument types repeatedly.

John McCall 942687084f __attribute__((aligned(n))) directly specifies the alignment of a declaration
unless it's a non-packed field, in which case it can only increase the

(because it's ill-formed for [[align]] to decrease alignment ever).

Chris Lattner 8473339100 Various builtins a require an integer constant. Not providing
one results in an obscure error from the backend that doesn't make
sense.  Capture this information in the .def files for builtins with
a new "I" modifier letter indicating the an argument needs to be an ICE.

Nothing uses this yet, but sema will eventually enforce this (eliminating
some special cases from semachecking.cpp) and codegen will use this to 
force an ICE value, preventing backend error messages.

Douglas Gregor 457104e98b Move the management of the set of conversion functions in a C++ class
into CXXRecordDecl. The only part that we do not handle this way are
using declarations, since that would require extra name lookup that we
don't currently want to pay for. This fixes <rdar://problem/8459981>,
so that LLDB can build a CXXRecordDecl and magically get all of the
right bits set.

Douglas Gregor 8fb9512966 Move the maintenance of CXXRecordDecl::DefinitionData's Abstract bit
completely into CXXRecordDecl, by adding a new completeDefinition()
function. This required a little reshuffling of the final-overrider
checking code, since the "abstract" calculation in the presence of
abstract base classes needs to occur in
CXXRecordDecl::completeDefinition() but we don't want to compute final
overriders more than one in the common case.

in CXXRecordDecl itself. Yes, this is also part of <rdar://problem/8459981>.

This reinstates r114924, with one crucial bug fix: we were ignoring
the implicit fields created by anonymous structs/unions when updating
the bits in CXXRecordDecl, which means that a class/struct containing
only an anonymous class/struct would be considered "empty". Hilarity
follows.
