[patch][committed] Don't include varray.h where it is not needed

[Steven Bosscher <stevenb dot gcc at gmail dot com>]

Hi,

Don't include varray.h where it is not needed -- which is to say,
include it nowhere except in toplev.c and sdbout.c.

Committed, pre-approved by Richi. I only include the ChangeLog below,
because the patch is so mechanical.
See http://gcc.gnu.org/viewcvs?view=revision&revision=158933 for the details.

Ciao!
Steven
