New implementation for constants
VLOCAL expressions keep a reference to their corresponding 'Vardesc', and 'Upvaldesc' (for upvalues) has a field 'ro' (read-only). So, it is easier to check whether a variable is read-only. The decoupling in VLOCAL between 'vidx' ('Vardesc' index) and 'sidx' (stack index) should also help the forthcoming implementation of compile-time constant propagation.
