Expand the boundary for "ref cycles" event test as it has
been observed that the results do not fit on some CPUs [1]:
FAIL: full-width writes: ref cycles-N
100000 >= 87765 <= 30000000
100000 >= 87926 <= 30000000

100000 >= 87875 <= 30000000

100000 >= 88161 <= 30000000
100000 >= 88052 <= 30000000
[1] Intel(R) Xeon(R) Platinum 8374C CPU @ 2.70GHz
Opportunistically fix cc1 warnings for commented print statement.
