This one I'm not too sure about:
The public fields of StandardCharsets are part of the public API, so they
definitely need to exist.  So let's create them directly (i.e. using "new",
not Charset.forName) and don't bother putting these fields anywhere else.

Motivation: I ran into trouble using reflection via
StandardCharsets.<clinit> too early during bootstrap with a local mod.
