SyntaxError: let is disallowed as a lexically bound name
Prohibit let in lexical bindings This patch prohibits lexical bindings from being called 'let', even in sloppy mode, following the ES2015 specification. The change affects multiple cases of lexical bindings, including simple let/const declarations and both kinds of for loops. var and legacy const bindings still permit the name to be let, including in destructuring cases. Tests are added to verify, though some cases are commented out since they led to (pre-existing) crashes.
