types.hpp: implement smin, smax, amin, amax
...
Rewritten the following global utility constants:
`umax` returns max number, restricted to unsigned.
`smax` returns max signed number, restricted to integrals.
`smin` returns min signed number, restricted to signed.
`amin` returns smin or zero, less restricted.
`amax` returns smax or umax, less restricted.
Fix operators == and <=> for synthesized rel-ops.
