Tune context allocation for variables accessed from inner scopes.
...
After introduction of with scopes we have enough static information to omit
context allocation in the case that a variable is accessed from a nested block
or catch scope of the same function. Only variables accessed from the inside of
a nested function or with scope are forced to be allocated in the context.
This essentially reverts

Fix error handling in Date.prototype.toISOString.
...
This fixes Date.prototyoe.toISOString to throw a RangeError exception
for invalid time values. It also includes a fix to removes the arbitrary
(and completely bogus) range limit on the date value during construction
of a Date object. Note that we still have bogus range limits on the year
and month values.
