Toon Verwaest 11a2522933 [parser] Cache scope-info-backed lookup results on entry scope 
We'll always lookup variables in the entry scope-info-backed chain through a
single entrypoint, hence we can cache any variables we create in that chain on
the entry-point's VariableMap. Otherwise we always have to redo all negative
lookups until we hit the scope that introduces it (the script scope being the
final possible scope to introduce it).

This should allow us to get rid of the ContextSlotCache as well.
