This implements a new nonunifom analysis suggested by @jbolz. This change generates nonUniform decorations that were previously missing and avoids generation of incorrect decorations. Most notably, it now generates decorations for nonuniform functions and out params. It avoids generating decorations for lvalues which themselves are not nonuniform.
