Ensure we have a lexical scope for global code
This requires a bit more work than simply pushing a
new BlockContext for the lexically declared variables,
as eval() and the Function constructor operate on the
global scope (including the lexically declared names).
To fix this introduce Push/PopScriptContext instructions,
that create a BlockContext for the lexically declared
vars and pushes that one as a global script context that
eval and friends use.
