[COMMITTED PATCH] Remove second (nested) copy of local var child_die.

[Doug Evans <xdje42 at gmail dot com>]

Hi.

This function was a bit confusing to read given
the outer child_die was initialized way early and used way late.

Committed.

	* dwarf2read.c (process_structure_scope): Remove second (nested) copy
	of local var child_die.
