Debug evaluate no longer writes back changes to the replicated
context chain to the original after execution. Changes to the
global object or script contexts still stick. Calling functions
that bind to the original context chain also have their expected
side effects.
As far as I can tell, DevTools is not interested in modifying
local variable values. Modifying global variable values still
works as expected. However, I have not yet removed the old
implementation, but merely keep it behind a flag.

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).
