among other things.

Also change a codegen warning to dump to stderr so it doesn't
mess with -emit-llvm output

Use copy for LHS, because it is incremented using ++ operator.

Dummy block is an empty block with no predecessors.

Move Decl::NextDeclarator (w/ setters/getters) down to ScopedDecl/FieldDecl.

Decl is now svelte:-)

This patch temporarily breaks compound assignment operators, but greatly simplifies many
things.

This means that we get rid of tons of intermediate allocas.  For
example:

void foo(double _Complex a, double _Complex b) {
   a = b+a+a;
}

this used to have 4 temporary allocas, now it has zero of them.
This also simplifies the individual visitor methods because they
now can all operate on real/imag pairs instead of having to 
load/store all over the place.

aggregate value and scalar expression computation are very different, this
gets them away from each other.  This causes a temporary regression on some
complex number examples.

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.
