Add CodeGen support for indirect goto.
- Follows emission scheme used by llvm-gcc, i.e. invent an id for
each label whose address is taken and replace each indirect goto by
a switch to each possible target.
- Currently we emit a switch for each indirect goto instead of
merging them as llvm-gcc does.

Rework codegen emission of globals
- No (intended) functionality change.

- Primary purpose is to clearly separate (lazy) construction of
globals that are a forward declaration or tentative definition from
those that are the final definition.

- Lazy construction is now encapsulated in
GetAddrOf{Function,GlobalVar} while final definitions are
constructed in EmitGlobal{Function,Var}Definition.

- External interface for dealing with globals is now limited to
EmitGlobal and GetAddrOf{Function,GlobalVar}.

- Also updated helper functions dealing with statics, annotations,
and ctors to be private.

First cut at setting attributes for functions and calls; this puts us
much closer to passing the gcc struct layout tests.

It might be possible to refactor this a bit, but I'm not sure there's
actually enough common code for that to be useful.

To get the calling convention completely correct, a bit of
platform-specific code is necessary even for x86-Linux. On x86-Linux, the
alignment of function parameters is extremely strange; as far as I can tell,
it's always 4 except for SSE vectors or structs containing SSE vectors. I'm
continuing to investigate this.

Make debugging information usable. This is barebones, but it makes -g
actually work (instead of crashing llc), and there's enough info emitted
to get line number information in gdb. This should hopefully be helpful
for debugging non-working programs.

I got rid of the begin/endregion calls because the implementation wasn't
working; someone who knows the debugging info a bit better might try to
add it. I really have no clue how a compiler is supposed to emit them.

This commit shouldn't have any effect without -g.

Move getAccessedFieldNo out of lib/AST/Expr.cpp into
lib/CodeGen/CGExpr.cpp and to change include/clang/AST/Attr.h to
use its own enum for visibility types instead of using

Remove FileVarDecl and BlockVarDecl. They are replaced by VarDecl::isBlockVarDecl() and VarDecl::isFileVarDecl().

This is a fairly mechanical/large change. As a result, I avoided making any changes/simplifications that weren't directly related. I did break two Analysis tests. I also have a couple FIXME's in UninitializedValues.cpp. Ted, can you take a look? If the bug isn't obvious, I am happy to dig in and fix it (since I broke it).

some cleanups on top of David's patch. There are still two
remaining open issues I've communicated to him:

1) self can be assigned to, and his patch didn't handle it correctly.
2) CollectObjCIvarTypes is N^2 (because each subclass reprocesses
all parent class ivars) and flattens classes. If A derives from B,
and both have an int, I'd expect to get { {i32}, i32}, not { i32, i32}.

David, please review.

Make a major restructuring of the clang tree: introduce a top-level
lib dir and move all the libraries into it. This follows the main
llvm tree, and allows the libraries to be built in parallel. The
top level now enforces that all the libs are built before Driver,
but we don't care what order the libs are built in. This speeds
up parallel builds, particularly incremental ones.
