Message:

Refactoring in tester and perf

Use can_cast_size_t_to_int instead of the body of this function.

Also replaced "if" with assert() as the overflow (see diff) can rarely
happen and actually denotes a problem with the test itself (really,
test name longer than MAX_INT is insane).

Notice how the code from kernel was ported to userspace without changes
to the error text that would printed .
