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 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.

Delete should return false if an element doesn't exist in a set.
ECMA_VALUE_EMPTY wasn't checked in case of a deleted property.

We need to check if we use the lastIndexOf method and if the second
argument is a number, negative, and its absolute value is bigger
than the length, then we should return with -1.

We should check if the start index is equal or greater than the end index,
if thats the case, we should return with the original typedArray.

Also made the parsing more strict (more issues were captured by the pre-scanner).
