AddBoundMethod, in i18n.js, returns functions all of which share the
same backing SharedFunctionInfo, which means that its calls to
InstallGetter were causing all such functions to have a single name
(that of the last caller, "get breakType").
This patch skips calling InstallGetter and instead directly calls
%DefineGetterPropertyUnchecked, which itself sets the name property
on the JSFunction instance (it knows how to do this in order to handle
getters that have computed property names).
Also takes care of a TODO having to do with the inner boundMethod:
its name is now made empty, by using a new macro that gets around
ES2015's function name inference.
Finally, removes a redundant %FunctionRemovePrototype: arrow functions
have no prototypes to begin with.

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.
