Add `set print repeats' tests for C/C++ arrays

Add `set print repeats' tests for C/C++ arrays, complementing one for
Fortran arrays and covering the different interpretation of the `set
print elements' setting in particular where the per-dimension count of
the elements handled is matched against the trigger rather than the
total element count as with Fortran arrays.
