Support initalisers for more than just int-typed static variables.

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

Rename FileVariable -> FileVar for consistency with its class name,

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.

Finally bite the bullet and make the major change: split the clang namespace
...
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.
