Joseph Ferano dad725afe4 The prelude's per-type families collapse: 22 functions become 10, 27 become 16 ...

swap!, reverse!, sort!, sort-by!, index-of, min-of, max-of, map!,
reduce and filter, each written once over $t. Every call site in the
corpus moves with them.

min-of and max-of are not min and max because min and max are builtins
over two or more numbers and nothing shadows a builtin. These reduce a
slice, which is a different operation at a different arity.

sort-bytes! did not collapse into sort!, and the reason is the point of
the predicates: a [u8] is not ordered? and cannot be, because < is an
instruction and comparing two slices lexicographically is a loop. It is
sort-by! with bytes<? written in, one line, keeping its name and its
stability note. sum-i32/sum-f32 and append-i64!/append-f64! stay for the
reasons the spike gave.

Not what the notes predicted: none of the ten collapses on a signature
change alone. filter and reduce need copyable? because the checker
demands it - reduce's accumulator at (Vec i32) is a double move - and
the rest declare it because a slice of owning elements would have them
duplicating headers.
