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

This change brings the replace operation up to date with ES6 by
implementing support for the @@replace well-known symbol, while
also improving performance and memory usage.
Also fixes#3070.

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.)

Various cbc opcodes are added to support the different instantiations.

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

Added hasInstance well known symbol implementation for Function.prototype.
This change however does not implement the ES2015 `instanceof` operator changes.

- 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.
This patch also fixes#3204.

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.

Fixes#3129
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.

The patch also checks whether pre-scanning is successful when scanning is,
so no need for explicit pre-scanner checks anymore.

The function names of classes were incorrectly parsed.
Also made the parsing more strict (more issues were captured by the pre-scanner).

The scanner was an on-demand tool of the parser, which was triggered by certain
statements. After the rework, the scanner runs only once, and collects all information.
This information is passed to the parser.

In case of TypedArrays which were constructed with an ArrayBuffer
the `slice` method incorrectly added the `byteOffset` value of
when the elements were copied.
There is no need to add the `byteOffset` value for the ArrayBuffer's
contents pointer as it is already added by the `ecma_typedarray_get_buffer`
call.

The "super prop ref" flag is incorrectly used at multiple expressions
as it was only cleared if there was an assignment operation.
