This patch supplies additional cleanups that were independently
developed testing C++20 on an M1 mac. After rebasing onto the
changes already landed in master, the main effect is to adopt
an additional library feature macro, in the style of existing
feature macros, rather than rely on inline tests for the C++
language version. Also added platform support for the Arm 9 CPU,
and fixed up a typo or two.
