littledan	95145fa826	Ship ES2015 sloppy-mode const semantics This patch moves the semantics of 'const' in sloppy mode to match those in strict mode, that is, const makes lexical (let-like) bindings, must have an initializer, and does not create properties of the global object.

Ship ES2015 sloppy-mode const semantics

This patch moves the semantics of 'const' in sloppy mode to match those
in strict mode, that is, const makes lexical (let-like) bindings, must
have an initializer, and does not create properties of the global object.

Fix a potential crash in const declaration.

Declaration of const lookup slots would trigger an assertion if there was a
setter somewhere in the prototype chain, and that setter was shadowed by a
non-readonly data property also in the prototype chain.
