use MIN fusion for ISL-14
This patch fixes PR66754 by reverting an earlier unintended change.
We now generate a much simpler AST for interchange-1.c:
ISL AST generated by ISL:
{
for (int c1 = 0; c1 <= 1334; c1 += 1) {
S_7(c1);
for (int c3 = 0; c3 <= 1334; c3 += 1)
S_4(c1, c3);
S_5(c1);
}
for (int c1 = 0; c1 <= 1334; c1 += 1)
S_10(c1);
S_8();
}
Bootstrap and check pass on x86_64-linux with isl-0.14.1

* graphite-optimize-isl.c (optimize_isl): Call
isl_options_set_schedule_fuse with ISL_SCHEDULE_FUSE_MIN for ISL-14.
