7a12ad0dc1 First cut at emitting debugging information for C++ member functions. 
There is lot more work to do in this area.

ddf6a57f3e llvm::Function name is the linkage name. If it has a '01' as a prefix then probably there is a reason.

2d63010a9c Emit linkage name even if it matches regular name. The code generator uses linkage name to find subprogram entry for the current function.

4274a326be Because CurLoc is the current source location as far as CGDebugInfo is concerned. It is expected that this is set (usually left bracket location of function body compound statement) before EmitfunctionStart() is used.

40775003e6 Roll out ASTContext::getTypeSizeInChars(), replacing instances of 
"ASTContext::getTypeSize() / 8". Replace [u]int64_t variables with CharUnits
ones as appropriate. 

Also rename RawType, fromRaw(), and getRaw() in CharUnits to QuantityType, 
fromQuantity(), and getQuantity() for clarity.

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!

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.

24c7f5efc5 Add -dwarf-debug-flags, which provides a way to embed the cc1 level options used 
to compile a translation unit into the debug info for that file.
 - Used by parts of Darwin build process to check compiler flags, etc.
 - <rdar://problem/7256886> clang does not emit AT_APPLE_flags

1b8fe5b716 First part of changes to eliminate problems with cv-qualifiers and 
sugared types. The basic problem is that our qualifier accessors
(getQualifiers, getCVRQualifiers, isConstQualified, etc.) only look at
the current QualType and not at any qualifiers that come from sugared
types, meaning that we won't see these qualifiers through, e.g.,
typedefs:

  typedef const int CInt;
  typedef CInt Self;

Self.isConstQualified() currently returns false!

Various bugs (e.g., PR5383) have cropped up all over the front end due
to such problems. I'm addressing this problem by splitting each
qualifier accessor into two versions: 

  - the "local" version only returns qualifiers on this particular
    QualType instance
  - the "normal" version that will eventually combine qualifiers from this
    QualType instance with the qualifiers on the canonical type to
    produce the full set of qualifiers.

This commit adds the local versions and switches a few callers from
the "normal" version (e.g., isConstQualified) over to the "local"
version (e.g., isLocalConstQualified) when that is the right thing to
do, e.g., because we're printing or serializing the qualifiers. Also,
switch a bunch of
  
  Context.getCanonicalType(T1).getUnqualifiedType() == Context.getCanonicalType(T2).getQualifiedType()

expressions over to 

  Context.hasSameUnqualifiedType(T1, T2)

5348515193 Do not eagerly set stop point for arguments. This misleads the debugger in identifying beginning of function body. Instead, create new location to attach with llvm.dbg.declare. This location is only used to find the context of the variable by the code generator, and it is not used to emit line number info.

c5b8225285 Remove the ConstantArrayType subtypes. This information is preserved in the 
TypeLoc records for declarations;  it should not be necessary to represent it
directly in the type system.

Please complain if you were using these classes and feel you can't replicate
previous functionality using the TypeLoc API.
