PATCH: Set size of long/ptr as well as sp/pc for x32

["H.J. Lu" <hongjiu dot lu at intel dot com>]

Hi,

This patch should be applied on top of

http://sourceware.org/ml/gdb-patches/2012-05/msg00460.html
http://sourceware.org/ml/gdb-patches/2012-05/msg00462.html

It sets size of long/ptr as well as sp/pc for x32.  OK to install after
the above patches are approved?

Thanks.

H.J.
