[commit] dwarf2read.c: Rename info_or_types_section to section.

[Doug Evans <dje at google dot com>]

Hi.
I liked the name of this member early on, but enough time has passed that
it's a bit verbose now.

Committed.

2013-03-28  Doug Evans  <dje@google.com>

	* dwarf2read.c (struct dwarf2_per_cu_data): Rename member
	info_or_types_section to section.  All uses updated.
	(struct dwo_unit): Ditto.
