ID/Stmt: Introduce INIT_SKIP and use in ForStmt

Browse source 
Currently, loop vars are added to a function scope's inits and
initialized upon entering a function with default values. This
applies to vector, record and table types.

This is unnecessary for variables used in for loops as they are
guaranteed to be initialized while iterating.
