Eric Christopher c87915629b Update for the intrinsic changes in llvm: the object size intrinsic 
only takes a boolean second argument now. Update tests accordingly.
Currently the builtin still accepts the full range for compatibility.

Anders Carlsson 8a35c7982c Make sure that we mangle overloaded operators that are member functions correctly, giving them the correct arity. 
With this seemingly insignificant fix, we are now able to build and link clang using clang itself! (LLVM still has to be built with gcc for the time being).

Daniel Dunbar 3780f0b680 x86_64: Structures with no fields but which have padding should be classified as 
integer.
 - This is consistent, but may not be correct. I will revisit x86_64 ABI handling for C++ as a whole at some point.
 - PR5831.

Douglas Gregor 0f139a1df1 Improve on my previous fix for debug information. Rather than 
recursing in CGDebugInfo::CreateTypeNode, teach
CanonicalizeTypeForDebugInfo---now called UnwrapTypeForDebugInfo---to
keep unwrapping the type until we hit something that can be
represented by debug information. Thanks to Anders for pointing this out!

Douglas Gregor 0915b43ac2 Teach debug info generation to handle TemplateSpecializationType, 
ElaboratedType, QualifiedNameType, and SubstTemplateTypeParmType type
nodes. Also, produce an "unsupported" diagnostic for C++0x type nodes
and "typeof" nodes, rather than asserting nondescriptly.

Daniel Dunbar e017ecc9e2 Remove ';' after method definition. Noticed by clang++, which one would think 
would have a higher respect for its own code. This is getting old, is this

Eli Friedman 70724ad2ff Work in progress for setting the vtable pointers for all bases correctly in 
the constructor.  This doesn't handle cases requiring the VTT at the moment,
and generates unnecessary stores, but I think it's essentially correct.

Ken Dyck 01e620efaa Change the return type of ASTContext::getTypeSizeInChars() from uint64_t to the 
new opaque value type, CharUnits. This will help us avoid accidentally mixing 
quantities that are in bit and character units.

Douglas Gregor e1314a64b8 Switch the initialization required by return statements over to the 
new InitializationSequence. This fixes some bugs (e.g., PR5808),
changed some diagnostics, and caused more churn than expected. What's
new:

  - InitializationSequence now has a "C conversion sequence" category
    and step kind, which falls back to
  - Changed the diagnostics for returns to always have the result type
    of the function first and the type of the expression second.
    CheckSingleAssignmentConstraints to peform checking in C. 
  - Improved ASTs for initialization of return values. The ASTs now
    capture all of the temporaries we need to create, but
    intentionally do not bind the tempoary that is actually returned,
    so that it won't get destroyed twice.
  - Make sure to perform an (elidable!) copy of the class object that
    is returned from a class.
  - Fix copy elision in CodeGen to properly see through the
    subexpressions that occur with elidable copies.
  - Give "new" its own entity kind; as with return values and thrown
    objects, we don't bind the expression so we don't call a
    destructor for it.

Note that, with this patch, I've broken returning move-only types in
C++0x. We'll fix it later, when we tackle NRVO.

Chris Lattner 2f3da9b205 update to match LLVM API change: 
Remove isPod() from DenseMapInfo, splitting it out to its own
isPodLike type trait.  This is a generally useful type trait for
more than just DenseMap, and we really care about whether something
acts like a pod, not whether it really is a pod.

Eli Friedman cd6a50f3e5 Make copy assignment operator synthesis not explode for classes with complex 
or non-record aggregate members.

It might be worth spending some time to optimize this code (and the parallel
code for copy constructors) to memcpy in larger chunks, rather than copying
one member at a time.  Not sure exactly how beneficial that would be, but
it seems like could help for large classes with, for example, a vtable pointer
forcing the generation of a copy constructor.
