It includes an algorithm for cloning declarative lexical environments.

Local variables inside the function body should be constructed after the
parameters are initialized. Furthermore arguments should be available
during parameter initialization.

Remove var declaration workarounds and correctly create / use variables for modules.
Still missing: create lexical environment for automatic module conversion.
(Or remove this feature overall.)

This patch implements the core part of let/const statements. Redeclarations are correctly
detected and separate contexts are correctly created for these statements. Register
optimizations are also emplyed whenever possible.
Lots of features are still missing:
- checking the var statements in eval
- const are treated as lets
- single statement checks are missing
- export declarations are exported as vars, let/const export is not supported

The pre-scanner now is able to track all variable declarations and produces a compressed
stream which store this data for each function and catch block. When a function or
catch block is parsed, this information is decoded and the appropriate variables are
created. Furthermore a stack scope is created which contains the currently available
local variables and their register or literal index.

- The structure members have been renamed and the members got more detailed description.
- Updated the usage of the typedarray info structure in all occurrences to use absolute addressing from the underlying arraybuffer pointer.

ES5.1 15.9.1.15 Note1 defines that 24:00 is same as 0:00
of the next day. The spec explicitly doesn't mention that
24:01 should be invalid, but it should be self-evident.
(FireFox and Chrome also refuses times bigger than 24:00)

The implementation was incorrect for negative years and years bigger than 9999.
-1 was 000/ because the negative (year%10) was added to '0' character, years
bigger than 9999 was truncated to 4 digits.
ES5.1 15.9.1.15.1 defines extended years format with 6 digits, but toString()
and toISOString() sections don't mention anything about extended years. ES6
20.3.4.3 already clarifies that Date.prototype.toISOString() should use this
extended year format if it is necessary.
Changes:
- Date.prototype.toString() uses 4 digits for years by default, 5 or 6 if it
is necessary and put '-' sign for negative years, no sign for positive years.
Date.prototype.toString() was implementation dependent until ES9, but ES9
already specify exactly this format.
- Date.prototype.toISOString() uses fixed 4 digits for years 0 - 9999,
otherwise sign + 6 digits (extended years).
- Tests added for corner cases.
