Folding statement: i_2 = 0;
Folded into: i_2 = 0;

Folding statement: i_3 = i_1 + 1;
Not folded
Folding PHI node: i_1 = PHI <i_2(2), i_3(3)>
Folded into: i_1 = PHI <0(2), i_3(3)>

Folding statement: if (i_1 <= 99)
which is likely CONSTANT
Not folded
Folding statement: return;
Not folded

This still happens on the trunk.
Simple testcase:
void foo(void){int i;for(i=0;i<100;i++);}
