Sloppy-mode function declarations in blocks are now hoisted appropriately. In ES2016, function declarations nested in blocks are formally allowed. This was never a part of ECMAScript, but was a common extension. Unfortunately implementations differed in the exact semantics. Annex B.3.3 in the spec tries to standardize the parts which are common to different implementations, but does so with some fairly complicated semantics. This CL addresses three issues related to annex B.3.3: * When the outer function had a complex parameter list, no hoisting whatsoever was being performed. * Hoisting was not blocked by parameters of the same name. * Hoisting was not blocked by nested lexical declarations of the same name. We had tests which checked for the second, but they were incorrectly passing due to the first. This CL adds more complete tests.
