- Use raw_ostream for output instead of std::string concatenation.
- Break long lines in a GCC (4.2) compatible manner.
- Output dependents in #included order (to match GCC).

- CastExpr is the root of all casts
- ImplicitCastExpr is (still) used for all explicit casts
- ExplicitCastExpr is now the root of all *explicit* casts
- ExplicitCCastExpr (new name needed!?) is a C-style cast in C or C++
- CXXFunctionalCastExpr inherits from ExplicitCastExpr
- CXXNamedCastExpr inherits from ExplicitCastExpr and is the root of all
of the C++ named cast expression types (static_cast, dynamic_cast, etc.)
- Added classes CXXStaticCastExpr, CXXDynamicCastExpr,
CXXReinterpretCastExpr, and CXXConstCastExpr to
Also, fixed returned-stack-addr.cpp, which broke once when we fixed
reinterpret_cast to diagnose double->int* conversions and again when
we eliminated implicit conversions to reference types. The fix is in
both testcase and SemaChecking.cpp.
Most of this patch is simply support for the renaming. There's very
little actual change in semantics.

using LexRawToken, create one and use LexFromRawLexer. This avoids
twiddling the RawLexer flag around and simplifies some code (even
speeding raw lexing up a tiny bit).
This change also improves the token paster to use a Lexer on the stack
instead of new/deleting it.

Reworked control flow to:
- rewrite the block expr body "in place".
- used Chris's new rewriter hook "getRewritenText" to "lift" the text for later use.
- finally, we do the block expr text replacement.

Need a couple tweaks to RewriteObjCTryStmt(). Need to deal with implicit finally clauses (to make sure objc_exception_try_exit is called). Also fixed a related bug where we need to generate an implicit @catch else clause (to again make sure objc_exception_try_exit is called).

This change effects both RecordDecls and CXXRecordDecls, but does not effect EnumDecls (yet).
The motivation of this patch is as follows:
- Capture more source information, necessary for refactoring/rewriting clients.
- Pave the way to resolve ownership issues with RecordDecls with the forthcoming
addition of DeclGroups.
Current caveats:
- Until DeclGroups are in place, we will leak RecordDecls not explicitly
referenced by the AST. For example:
typedef struct { ... } x;
The RecordDecl for the struct will be leaked because the TypedefDecl doesn't
refer to it. This will be solved with DeclGroups.
- This patch also (temporarily) breaks CodeGen. More below.
High-level changes:
- As before, TagType still refers to a TagDecl, but it doesn't own it. When
a struct/union/class is first referenced, a RecordType and RecordDecl are
created for it, and the RecordType refers to that RecordDecl. Later, if
a new RecordDecl is created, the pointer to a RecordDecl in RecordType is
updated to point to the RecordDecl that defines the struct/union/class.
- TagDecl and RecordDecl now how a method 'getDefinition()' to return the
TagDecl*/RecordDecl* that refers to the TagDecl* that defines a particular
enum/struct/class/union. This is useful from going from a RecordDecl* that
defines a forward declaration to the RecordDecl* that provides the actual
definition. Note that this also works for EnumDecls, except that in this case
there is no distinction between forward declarations and definitions (yet).
- Clients should no longer assume that 'isDefinition()' returns true from a
RecordDecl if the corresponding struct/union/class has been defined.
isDefinition() only returns true if a particular RecordDecl is the defining
Decl. Use 'getDefinition()' instead to determine if a struct has been defined.
- The main changes to Sema happen in ActOnTag. To make the changes more
incremental, I split off the processing of enums and structs et al into two
code paths. Enums use the original code path (which is in ActOnTag) and
structs use the ActOnTagStruct. Eventually the two code paths will be merged,
but the idea was to preserve the original logic both for comparison and not to
change the logic for both enums and structs all at once.
- There is NO CHAINING of RecordDecls for the same RecordType. All RecordDecls
that correspond to the same type simply have a pointer to that type. If we
need to figure out what are all the RecordDecls for a given type we can build
a backmap.
- The diff in CXXRecordDecl.[cpp,h] is actually very small; it just mimics the
changes to RecordDecl. For some reason 'svn' marks the entire file as changed.
Why is CodeGen broken:
- Codegen assumes that there is an equivalence between RecordDecl* and
RecordType*. This was true before because we only created one RecordDecl* for
a given RecordType*, but it is no longer true. I believe this shouldn't be too
hard to change, but the patch was big enough as it is.
I have tested this patch on both the clang test suite, and by running the static analyzer over Postgresql and a large Apple-internal project (mix of Objective-C and C).

- gcc is not happy if we start a preprocessed file with
#line 1 "XXX" 1
- Workaround by making sure file starts with a simple #line change.
Also, factored WriteLineInfo out.
Also, fixed bug where FileType was not being correctly updated.

The motivation behind this change is that chaining the RecordDecls is simply unnecessary. Once we create multiple RecordDecls for the same struct/union/class, clients that care about all the declarations of the same struct can build a back map by seeing which Decls refer to the same RecordType.
