Statically check for assignments to const in harmony mode. · 08b42625

The ES.next draft rev 4 in section 11.13 reads:
It is a Syntax Error if the AssignmentExpression is contained in extended code
and the LeftHandSideExpression is an Identifier that does not statically resolve
to a declarative environment record binding or if the resolved binding is an
immutable binding.

This CL adds corresponding static checks for the immutable binding case.
