   ObjCMethodDecl via dyn_cast).

This fix just makes sure to construct the global with the appropriate 
type, and fixes up the one user this affects to compensate.

llvm::Type::isSingleValueType. Currently these two functions have
the same behavior, but soon isFirstClassType will return true for
struct and array types.

Clang may some day want to use of isFirstClassType for some of
these some day as an optimization, but it'll require some
consideration.

as globals).

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).

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.

We now use the CodeGenModule logic for generating the constant 
initialiser expression, so happily further initialiser fixes should 
automatically work for statics as well.

likewise block and param.  Reorder the layout of the Decl kind enum
so that the inheritance tree is reflected in the ordering.  This allows
trivial range comparisons to determine whether something is an instance
of some abstract class, making classof faster.

out of the llvm namespace.  This makes the clang namespace be a sibling of
llvm instead of being a child.

The good thing about this is that it makes many things unambiguous.  The
bad things is that many things in the llvm namespace (notably data structures
like smallvector) now require an llvm:: qualifier.  IMO, libsystem and libsupport
should be split out of llvm into their own namespace in the future, which will fix
this issue.
