<li>The <tt>IRBuilder</tt> class is now parametrized by a class responsible
for constant folding. The default ConstantFolder class does target independent
constant folding. The NoFolder class does no constant folding at all, which is

<li>LLVM now supports "function attributes", which allows us to separate return
value attributes from function attributes. LLVM now supports attributes on a
function itself, a return value, and its parameters. New supported function
