Implement the dead temporal zone
With const and let it is possible to access the declared member before
initialization. This is expected to throw a type reference error at
run-time.
We initialize such variables with the empty value when entering their
scope and check upon access for that. For locals we place the lexically
scoped variables at the end. For register allocated lexical variables we
group them into one batch and remember the index/size.
