The bytearray_repeat and bytearray_irepeat are inefficient for small arrays and a high number of repeats.
This can be improved by using the same approach is in the corresponding bytes_repeat method.


python -m pyperf timeit "b=bytearray([1,2,])*100" 

Mean +- std dev: [base100] 479 ns +- 29 ns -> [patch100] 274 ns +- 18 ns: 1.75x faster

python -m pyperf timeit "b=bytearray([1,2,])*1000"

Mean +- std dev: [base1000] 2.58 us +- 0.18 us -> [patch1000] 399 ns +- 26 ns: 6.46x faster
