RE: SMS in gcc4.0

Hi, all

This patch will fix doloop_register_get defined in 
modulo-sched.c, and let the program of PI caculation 
on IA-64 be successfully modulo scheduled. On 1GHz 
Itanium-2, it costs just 3.128 seconds to execute when 
compiled with "-fmodulo-shced -O3" turned on, while 
5.454 seconds whithout "-fmodulo-sched".

	* modulo-sched.c (doloop_register_get): Deal 
with if_then_else pattern.
