[es6] Ensure that for-in/of loops have a proper TDZ for their
lexically-bound variables
The enumerable expression in a for-in/of loop is supposed to have a TDZ for
any
lexically bound names in that loop (there can be more than one with
destructuring).
This patch accomplishes this with an almost-correct desugaring. The only
thing missing
is proper debugger support (the let declarations added by the desugaring,
while invisible
to code due to shadowing, are visible to the debugger).
