[commit] dwarf2read.c cleanup

[dje at google dot com (Doug Evans)]

Hi.

fyi, I committed this minor cleanup to dwarf2read.c.
It just moves a function next to the other functions of its kind.

2012-07-02  Doug Evans  <dje@google.com>

	* dwarf2read.c (maybe_queue_comp_unit): Move definition next to others
	related to queue management.
