Note here is the reduced C testcase which shows that this is not PHI-OPT bug as
PHI-OPT does nothing:
int g(void);
void h(int);
int a1[2]={0,1};
int main(void)
{
int a = g();
_Bool i = a==2;
h(a1[i]);

Here is the most reduced testcase I came up with (this might be another type
mismatch problem in
tree-ssa-phiopt but I could be wrong if you replace a1[0][i] by a[0][a==2] it
works):
int g(void);
void h(i

OK, thanks, I'll go fix it. I mostly put it in here in case somebody was
working on a dup.

there is we don't compare
D.2150 to 2 at all.
