448a228521 fix some more cases where we'd emit a file with a line of 0 for implicit
types.  In this case, it was objc_selector and objc_class.  This fixes

f216fd96fe Do not generate bogus location info for DW_TAG_inheritance

These tags do not need locations at all, just remove it.

a6acb390e7 Handle corner case where clang-cc is invoked directly to compile preprocessed source file without -main-file-name. In this case, CDDebugInfo is not able identify correct main source file becase SM.isFromMainFile() returns true for locations from header files as well as locations from main source file.
This patch takes conservative approach by not emitting more then one compile unit with isMain bit set.

3b358a3d83 Make debug info work when using -save-temps.
- This is pretty ugly, but the most obvious solution. Chime in if you
   have a nicer one.

 - The problem is that with -save-temps, clang-cc has no idea what the
   name of the original input file is. However, the user expects to be
   able to set breakpoints based on the input file name.

 - We support this by providing a new option -main-file-name (similar
   to -dumpbase used by gcc) which allows the driver to pass in the
   original file name.

 - <rdar://problem/6753383> building with clang using --save-temps
   gets the compile unit name from the .i file...

types.  It is no longer needed now that the code generator 
re-lays-out interfaces if they are defines after being laid out

dc572a3266 Improve the representation of template names in the AST. This
representation handles the various ways in which one can name a
template, including unqualified references ("vector"), qualified
references ("std::vector"), and dependent template names
("MetaFun::template apply").

One immediate effect of this change is that the representation of
nested-name-specifiers in type names for class template
specializations (e.g., std::vector<int>) is more accurate. Rather than
representing std::vector<int> as

  std::(vector<int>)

we represent it as

  (std::vector)<int>

which more closely follows the C++ grammar. 

Additionally, templates are no longer represented as declarations
(DeclPtrTy) in Parse-Sema interactions. Instead, I've introduced a new
OpaquePtr type (TemplateTy) that holds the representation of a
TemplateName. This will simplify the handling of dependent
template-names, once we get there.

5253768ada Introduce a representation for types that we referred to via a
qualified name, e.g., 

  foo::x

so that we retain the nested-name-specifier as written in the source
code and can reproduce that qualified name when printing the types
back (e.g., in diagnostics). This is PR3493, which won't be complete
until finished the other tasks mentioned near the end of this commit.

The parser's representation of nested-name-specifiers, CXXScopeSpec,
is now a bit fatter, because it needs to contain the scopes that
precede each '::' and keep track of whether the global scoping
operator '::' was at the beginning. For example, we need to keep track
of the leading '::', 'foo', and 'bar' in
 
  ::foo::bar::x

The Action's CXXScopeTy * is no longer a DeclContext *. It's now the
opaque version of the new NestedNameSpecifier, which contains a single
component of a nested-name-specifier (either a DeclContext * or a Type
*, bitmangled). 

The new sugar type QualifiedNameType composes a sequence of
NestedNameSpecifiers with a representation of the type we're actually
referring to. At present, we only build QualifiedNameType nodes within
Sema::getTypeName. This will be extended to other type-constructing
actions (e.g., ActOnClassTemplateId).

Also on the way: QualifiedDeclRefExprs will also store a sequence of
NestedNameSpecifiers, so that we can print out the property
nested-name-specifier. I expect to also use this for handling
dependent names like Fibonacci<I - 1>::value.

deaad8cc34 Create a new TypeNodes.def file that enumerates all of the types,
giving them rough classifications (normal types, never-canonical
types, always-dependent types, abstract type representations) and
making it far easier to make sure that we've hit all of the cases when
decoding types. 

Switched some switch() statements on the type class over to using this
mechanism, and filtering out those things we don't care about. For
example, CodeGen should never see always-dependent or non-canonical
types, while debug info generation should never see always-dependent
types. More switch() statements on the type class need to be moved 
over to using this approach, so that we'll get warnings when we add a
new type then fail to account for it somewhere in the compiler.

As part of this, some types have been renamed:

  TypeOfExpr -> TypeOfExprType
  FunctionTypeProto -> FunctionProtoType
  FunctionTypeNoProto -> FunctionNoProtoType

There shouldn't be any functionality change...
