Fixed a few address-space bugs while I was there.

a glvalue as a temporary. Previously, we were enumerating all of the
cases that coul return glvalues and might be called with
Sema::MaybeBindToTemporary(), but that was gross and we missed the
Objective-C property reference case.

code path and is more involved (TBD).

  - BlockDeclRefExprs always store VarDecls
  - BDREs no longer store copy expressions
  - BlockDecls now store a list of captured variables, information about
    how they're captured, and a copy expression if necessary
    
With that in hand, change IR generation to use the captures data in       
blocks instead of walking the block independently.        

Additionally, optimize block layout by emitting fields in descending
alignment order, with a heuristic for filling in words when alignment
of the end of the block header is insufficient for the most aligned
field.

Fix self-host; if a thunk already exists and has available_externally linkage, we should change its linkage instead of asserting.

llvm-svn: 124986

When building with optimizations, emit thunks with available_externally linkage so devirtualized function calls can also be de-thunked.

templates, a C++0x feature.

overridden via remapping. Thus, when we create a "virtual" file in the
file manager, we still stat() the real file that lives behind it so
that we can provide proper uniquing based on inodes. This helps keep
the file manager much more consistent.

To take advantage of this when reparsing files in libclang, we disable
the use of the stat() cache when reparsing or performing code
completion, since the stat() cache is very likely to be out of date in
this use case.

llvm-svn: 124971

Basic implementation of inherited constructors. Only generates declarations, and probably only works for very basic use cases.

llvm-svn: 124970

won't assert when building a thunk for an implicit virtual member function that is not marked used.

llvm-svn: 124967

A common pattern in classes with multiple initializers is to put the
subclass's common initialization bits into a static function that receives
the value of 'self', e.g:

   if (!(self = [super init]))
     return nil;
   if (!(self = _commonInit(self)))
     return nil;

It was reported that 'self' was not set to the result of [super init].
Until we can use inter-procedural analysis, in such a call, transfer the
ObjCSelfInitChecker flags associated with 'self' to the result of the call.

say "out-of-line definition differ from the declaration in the return type" instead of
the silly "functions that differ only in their return type cannot be overloaded".

We now emit everything except unused implicit virtual member functions when building the vtable.

id-expression, e.g., 

  CurrentClass<T>::member

Previously, if CurrentClass<T> was dependent and not complete, we
would treat it as a dependent-scoped declaration reference expression,
even if CurrentClass<T> referred to the current instantiation.

it's okay for the following template parameters to not have default
arguments (since those template parameters can still be
deduced). Also, downgrade the error about default template arguments
in function templates to an extension warning, since this is a
harmless C++0x extension.
