[PATCH, i386]: Use INTEGER_CLASS_P macro in ix86_spill_class

[Uros Bizjak]

Hello!

The patch replaces open-coded INTEGER_CLASS_P macro with its
definition from i386.h

2013-02-08  Uros Bizjak  <ubiz...@gmail.com>

        * config/i386/i386.c (ix86_spill_class): Use INTEGER_CLASS_P macro.

Bootstrapped and regression tested on x86_64-pc-linux-gnu {,-m32},
with additional configure flags "--with-arch=corei7
--with-cpu=corei7".

Committed as obvious to mainline SVN.
