...
Differences with __builtin_memcpy are it does not generate
extra calls and it can work only with compile time sizes.

Fix the helper function which returns random (exprand-style) file

offsets for fuzzing.
It didn't do proper job (as per #360 ), so it's been replaced by
something simpler. Now it's still prefering smaller values, but it's
a step function-like distribution now.
