Local functions lose scope when called from outside (compiled with dynamic scopes, optlevel >= 0)
Fix: ignore dynamic scope for nested functions and functions declared within
the with statement.
The patch makes optimizer to behave in the same way as the interpreter does
with regard to dynamic scope: it ignores it for nested functions and functions
declared under with statements. Now parser checks for such functions and set
new flag itsIgnoreDynamicScope in FunctionNode. The flag then checked both by
interpreter and optimizer during byte code generation.
The patch also changes slightly interaction between changing dynamic scope flag
and interpreted Script instances. Currently the dynamic flag is read during
script execution but patch changes interpreter to behave exactly as the
optimizer does: the dynamic flag only affect script compilation, changes in its
value does not affect already compiled scripts.
