[Bug target/15623] New: nop insertion does not look see restrict pointers

[pinskia at gcc dot gnu dot org]

Compile with -O2 -mcpu=power4 and see that both functions are the same but the second one should 
not have nops as we know that they are located at different places in memory as their declared as 
restrict:

int zero_restrict_pointers(int *p, int *q)
{
        *p = 0;
        return *q;
}
int two_restrict_pointers(int *restrict p, int *restrict q)
{
        *p = 0;
        return *q;
}
