Remove some unused overlay code
This patch removes some unneeded initializations in overlay code in
symfile.c. It also deletes some old commented-out code.
2016-06-06 Tom Tromey <tom@tromey.com>
* symfile.c (simple_overlay_update_1): Remove initialization
of "size", and commented-out code.
(simple_overlay_update): Likewise.
