7dbff5b9e6 abs: remove support for floats. Use floats.fabs() instead.
this solves: can't use abs() etc in pipe expression because return type depends on argument type

220246278a removed sum(), max(), min(). abs() now always returns uword type.
This greatly simplifies internal handling of builtin functions by always having one fixed return type.
