Properly handle SINT_MIN in small_to_big()
As there is no overflow for signed integers, -SINT_MIN is undefined behaviour
and the cast to unsigned needs to happen before negation. SINT_MIN denotes the
minimum value that can be stored in the Sint type.
beam/big.c:1512:6: runtime error: negation of -9223372036854775808 cannot be represented in type 'Sint' (aka 'long'); cast to an unsigned type to negate this value to itself
