Some minor restructuring around LValue and RValue types. The value "kind" information is not separated into a "base" and "sub" type. Eventually the value-tracking logic will know about LValues and RValues, but not about specialized LValues and RValues; separating the "kind" information into bits indicating whether an ExprValue is an LValue or an RValue from the bits that specify the actual value type makes this separation easier.
