erts: Ensure hashing of zero is consistent
Erlang treats positive and negative zero as equal, meaning, true = 0.0 =:= 0.0/-1 However, Erlangs hash functions: hash, phash and phash2 did not reflect this behaviour. Meaning, the hash values produced by the different hash functions would not be identical for positive and negative zero. This commit ensures that hash value of positive zero is always produced regardless of the signedness of the zero float, i.e. true = erlang:phash2(0.0) =:= erlang:phash2(0.0/-1)
