variable redeclaration in for-of statement

Version: 7142b0d211b732e1c119fded80f43fbbd9cea0f8
What steps will reproduce the problem?

d8> try { } catch (e) { for (var e of []) {} }
undefined
2. Run in d8
d8> try { throw null } catch (e) { eval("for (var e of []) {}") }
undefined

runtime error for the eval case)
