Remove the special handling of spawn BIFs

BIFs that spawn new processes once upon a time needed/benefited
from special handling, but now they are handled in exactly the
same way as an unsafe BIF (except for a bug in the handling of
the return value trace). Therefore, treat spawn BIFs as unsafe
BIFs.
