When the testcase was being adjusted for unsigned long -> unsigned long long,
two spots using long weren't changed to long long, so the testcase still warns
about UB in shifts.
Excess errors:
.../gcc/gcc/testsuite/gcc.dg/vect/vect-early-break_100-pr113287.c:28:48:
warning: right shift count >= width of type [-Wshift-count-overflow]
Fixed thusly, committed to trunk as obvious.

* gcc.dg/vect/vect-early-break_100-pr113287.c: Use long long instead
of long.
