adamk b6e9f625c1 [es6] Self-assignment in a default parameter initializer should throw 
The first bug was that there are two different "initialization positions"
passed into PatternRewriter::DeclareAndInitializeVariables, and we weren't
setting them all properly for this case.

After further code review, it became clear that we weren't even recording
the correct position (the end of the initializer expression).

The combination of those two bugs caused the hole check elimination code
in full-codegen to skip emitting a hole check.

This patch takes care of both of those things. A follow-up will try
to reduce the number of "initializer positions" we track in the
variable declaration code.
