simpler C testcase

This testcase needs less flags to reproduce:

$ gcc -O -frerun-cse-after-loop -fschedule-insns2 -fselective-scheduling2
-fno-tree-ch -funroll-loops --param=max-sched-extend-regions-iters=112
--param=max-sched-region-blocks=43 testcase.c         
testcase.c: In function 'foo':
testcase.c:14:1: internal compiler error: in code_motion_path_driver, at
sel-sched.c:6575
