This reverts commit e8e4aca955.
Reason for revert: can break ES2 for-loop rules
Original change's description:
> Declare all inlined variables at the topmost scope possible.
>
> By itself, this is uninteresting and even perhaps slightly
> counterproductive (as it separates vardecl from its initializer,
> increasing LOC). However, this enables a followup CL
> (http://review.skia.org/344665) which allows single-return functions to
> be inlined without the creation of a temporary variable at all. This
> applies to the majority of fragment processors in a typical Ganesh
> hierarchy. This change will greatly reduce the number of inliner-created
> temporary copies when compiling a typical tree of FPs.
